Studio 6.3

QForMe premium waiters

A new class of waiters has been added to Studio. Premium waiters augment the standard waiter functionality by providing a mechanism to pass call related information to the agent. For example, you can extract information about the caller/call from the CRM and have it played back to the agent using Text-to-Speech. You can also have the caller record a short message and have that played back to the agent prior to transferring the call. For more information on premium waiters please visit the resource center.

For a tutorial & demo on QforMe Premium Waiters click the video below.

AMD enhancements

We have improved AMD handling in Studio 6.3 by splitting the AMD handler into two different event handlers - Machine detection and Beep detection. The Machine detection event handler triggers within 3 seconds of the call being answered, providing users an option to have a different call flow scenario when a machine is detected. The Beep detection event handler is ideal for leaving voicemail messages as it gets triggered after the voicemail beep signal is detected. See the reference on campaigns and voicemail systems for more information.

NLU enhancements

We have improved our Natural Language Understanding functionality by supporting a number of enhancements that were announced by Google last month. The Cloud Speech-to-Text node uses an enhanced phone model when using US English as the recognition language. This model provides upto 40% improvement in transcription accuracy over the default models that were used before. We have also increased the maximum number of phrase hints that can be passed from 500 to 5000. We have also included support for Dialogflow’s auto speech adaptation feature which improves the speech recognition accuracy of your agent.

Studio 5.3

webRTC integration with Studio

webRTC has grown in popularity and is supported natively by majority of the browsers today. This integration allows Studio to accept a webRTC call and answer it using a Studio voice task. webRTC extends the reach of Studio to web browsers as a potential endpoint for voice calls.

In this initial release we have restricted webRTC access from within the Studio web portal.

We have also introduced a play task feature that allows you to test your task without the need to map phone numbers to your task. This is helpful for debugging and prototyping call flows.

  1. To access play task feature simply access the call flow canvas for any Voice Task.
  2. At the top right hand side of the canvas, select the green phone icon. This will start the test call and play through the task as if it were a live phone call including DTMF inputs.
  3. To end the test call press the hangup button or simply wait for the call flow to end.


Make sure you have a microphone set up to allow voice inputs to your call flow. Audio will be played back through your device speakers.

SMS short codes

SMS campaigns support the use of SMS short codes. Standard SMS numbers have a limit in terms of the number of SMSs that can be sent per second. Short codes allow you to send SMS messages in bulk at a rate of approximately 100 messages per second. This is ideal for running large list-based campaigns. All campaigns for messaging tasks in Studio 5.3 will automatically include the new speed.

Support for confusables

The Form Node has been extended to include support for confusables. If you have a custom form type you will have an option to save the speech recognition results in an array variable. This means if your form type has items that are similar sounding, you can get back all the matching items. Please refer to the resource center to learn how to use this feature.

Other features and improvements

Studio 5.2

Open Speech

Studio 5.2 offers Open Speech functionality allowing you to transcribe user utterances and store the transcribed text as variables. We currently supports two speech platforms – Google Cloud and IBM Watson. You simply select the platform of your choice, configure your user prompts and Studio will do the rest!

Natural Language Processing

To complement the open speech capabilities, we have also introduced natural language processing within Studio. You have the option to use the Keyword Finder node or the more advanced Dialogflow node.

The Keyword Finder node makes it easy to match keywords or extract information such as email addresses and account numbers from unstructured text. The Dialogflow node simplifies the process of using the Google Dialogflow service by offering a visual interface to access your Dialogflow agents.

Secure Channel (HIPAA)

Studio 5.2 is HIPAA compliant. If you have a need to protect health information that you collect from your users, you can create HIPAA compliant tasks. Simply enable the HIPAA compliant option when you create a new task and Studio will ensure that your task is executed in a secure environment that has been certified HIPAA compliant.

HIPAA Compliance Requirements

  1. Note that Studio provides a platform for you to create HIPAA compliant tasks. As a Studio user, it is your responsibility to follow these requirments to ensure that your task is HIPAA compliant.
  2. Studio provides a secure channel for you to capture patient health information (PHI) and transmit it to the relevant organisation. Studio does not provide a mechanism to store patient information within its data center. Therefore, it is important that you never store PHI in Studio using the Datastore, Table, or Log nodes.
  3. Always use task-level variables to capture PHI. Never use global variables when capturing sensitive PHI data.
    You are free to use the standard Form or Menu node to capture PHI data from the user.
  4. When sending sensitive data to third-party CRM systems, make sure that the APIs are secure and they use some form of authentication (Basic, OAuth, etc).
  5. Do not use PHI data in conjunction with Open Speech or Dialog Flow nodes as it will break compliance.

Enabling Secure Channel (HIPAA)

  1. From the Task settings page select the Secure Channel (HIPAA) toggle at the bottom of the page.
  2. Select Save.
  1. From the Tasks page, any task that is using the Secure Channel will have the padlock icon next to the task name.

Bulk Phone Numbers Map/Unmap

The phone number controller within Studio has been extended to support bulk mapping and un-mapping of phone numbers. This feature is also supported via Studio APIs.

  1. From the Studio Portal, under Home in the top menu select Phone Numbers.
  1. From the List Phone Numbers page, click the Bulk Move button.
  1. From the Actions section, choose whether to wish to Bulk Map or Bulk Unmap numbers via the radio button.
  2. You can also Download Existing Mapped Phone Number List as a CSV to modify if applicable.
  3. To upload the Phone Number list that would like to Map or Unmap you can select the Browse button or simply drop the CSV file onto the page.
  1. Once you have provide the CSV number list you will need to select the Account/ Tasks where you would like to Map/Unmap the numbers.
  2. Finally, select the Map/Unmap Phone Numbers button.

Studio 5.1

Improved script creation workflow

Studio 5.1 introduces an improved workflow for creating IVR & SMS scripts. Providing a better user experience and allowing access to the powerful Studio App Library.

Any time you create a new script Studio will walk you through the four main ways you can create a call flow.

Studio App Library

When creating a new script you have the option to choose a ready-made script from the Studio App Library. These apps can serve as a great starting place for your final script and bring a lot of functionality 'out-of-the-box.'

  1. Select App Library from the script creation screen.
  1. Select the App you wish to use and click Next.
  1. The Script settings is the same as previous versions but with a refreshed interface. You can now toggle on/off AMD detection etc.

<img src="/images/logo/new_script.png" style="width:40em"">

Script Versioning

You can now save scripts as different versions and restore to any previously saved version. This provides security when updating scripts with new enhancements or testing changes to your call flow.

  1. From the call flow edit screen select the vertical ellipses "More Options" icon at the top right hand side of the canvas. From here you can vew your Version History and Save Version. If you have not yet saved a version then your version history will be empty.
  2. Select Save Version.
  1. On the following popup menu you can add a note to your version. This is helpful to give context for each of your versions but is not compulsory. Each Saved Version will automatically have a name associated with the script name (in this case "welcome") as well as a timestamp.
  1. Select Version History from the more options menu.

  2. You will see the recently saved version and the message we added earlier.

  3. From the Version History page you can also restore to any of your Saved Versions. As a backup safety measure, any time you restore to a Saved Version, Studio will automatically save the current state of your callflow to a new version with the description Autosave. This is to ensure you don't lose any data during a restoration.

Studio App library

Studio templates are now available via the app library. When you create a new script and select the app library option, you will be provided with all the pre-built templates that you have access to. Apart from a name, templates now have an icon and an optional short description.

Script Versioning

We have introduced script versioning in Studio. This feature allows you to save a version of a script at any point in time and roll back to a previously saved version of the script.

Voice Transcription

We have added the ability to transcribe recorded audio. Any recorded audio file that has been stored in Studio can be transcribed. Please note that this is a paid feature. Learn more.

Other features and improvements

  • A service number controller has been introduced in Studio making it easy to map and un-map service numbers to scripts.

We have completely re-designed the call flow editor with a drag and drop interface. The interface makes it easy to create and edit scripts. We have grouped all the nodes into different categories based on their functionality making it easy to find relevant nodes when building scripts. We have also introduced a new concept called Quick Nodes that provides quick access to your favourite nodes making it easy to build scripts.

Custom URL for Service Providers

Service Providers can setup a custom login page to access Inference Portal. This feature allows them to customise the login page with their logo and select a sub-domain of their choice. The feature can be configured by logging into Studio portal and updating your profile. Refer to the resource centre to learn more about this feature.

SMS conversations

We have extended our SMS channel to support conversation mode. Using this feature, you can build SMS apps that can have a conversation with your end users. If a user responds within a pre-defined time, conversation mode provides the ability to continue the conversation and ask follow up questions or perform a different action. To learn more about conversation mode, follow the how-to guide in the resource centre.

Node logging

The Node logging feature provides the ability to log call data without the need for a Log node. Once you enable Node logging on any script, Studio will log information about each call as it traverses through the different nodes and send that information to an external data warehouse (currently Google firebase in supported). Please note this feature is in beta and only a limited set of nodes are supported in this release. Refer to the resource centre for more information on how to use this feature, the supported nodes and the information logged.

Triggering a workflow will require Inference credits

Starting from Studio 5, workflows will be charged using Inference credits. If you are using workflows in your applications, please contact your service provider or Inference to purchase credits. A workflow reporting section has been added to access reports on your workflow usage.

Deprecated features

  • Play Prompt (Dynamic TTS) node has been deprecated. If you are using this node in your application, you should switch to a Complex prompt node.
  • Payment node has been deprecated. If you are using the Payment node in your application, you should switch to the new payment method that was introduced in Studio 4.2. The new payment method offers flexibility around designing your payment application as it uses the regular form nodes for collecting credit card details and separates the payment processing into an easy to use Payment Processing node. To learn more on how to do PCI compliant payments, follow the how to guide in the resource centre.
  • The old web theme (Classical theme) has been deprecated. If you are still using the classical theme, now is a good time to switch to the new theme which has a much better user interface that is updated regularly.
