Voice extension for Rasa
CVG turns chatbot into voicebot
Voice-controlled assistants take the customer experience to a new level. With VIER Cognitive Voice Gateway you can turn your text-based bot into a voicebot that listens and talks to your callers.
With CVG, VIER provides a voice extension for Rasa to turn your chatbot programmed in Rasa into a voicebot. CVG enables your chatbot to:
Speech-to-Text (STT)
High-quality speech recognition, e.g. with Microsoft Azure, Google Cloud and IBM Watson. Specially trained language models can be used for the recognition of specific terms.
Text-to-Speech (TTS)
CVG uses the voices of Amazon Polly, Microsoft Azure, Nuance, Google Cloud and IBM Watson to generate the most natural speech output possible. With SSML (Speech Synthesis Markup Language), the speech output can be further optimised.
Contact Center Integration
There are already existing integrations with some contact centre platforms, and other solutions can be connected via open APIs.

Create your own voicebot with Rasa and CVG
Your voicebot in 3 steps
Install Rasa and develop bot
Rasa can be installed anywhere: in the cloud, on premise or in any data centre. Many companies developing chatbots and voicebots with Rasa start with Rasa open source on-premise. An installation guide is provided by Rasa. Rasa also provides a playground that can be used to develop bots without requiring an on-premise installation.
The colleagues in our Professional Service Team will be happy to support you in the development of your bot.
CVG Channel in Rasa
To create voicebots with Rasa and CVG, use our VIER CVG channel, which is provided in a separate package on GitHub. It needs to be installed as part of your Rasa installation and works with both Rasa Open Source and Rasa Enterprise.
This VIER CVG channel in Rasa implements all CVG APIs relevant to bots to give you, the Rasa developer, the full power of CVG.
CVG account
In order for your bot to have a voice, you need a VIER CVG account. You can apply for one here. To configure the connection between your Rasa bot and CVG, simply select Rasa as your bot template in the CVG interface, enter your Rasa URL and token in the CVG project settings. That's it.
Possible tasks for a voicebot
Below are a few sample tasks that your new Voicebot could take on.
Intelligent recognition of user concern
Bots analyse and understand incoming communication on a semantic level and are thus able to quickly and reliably identify the concerns of your customers on the phone.
Reliable routing
Bots enable automatic routing to the right place in your company in written or verbal dialogue - quickly and very simply on the basis of short dialogues!
Identify relevant information
The AI collects essential information such as address data, customer and order numbers live and in real time during the ongoing dialogue and can thus respond to your customers in a more targeted manner.
Agent Assistance
Additionally, support your agents with live transcription and information retrieved from your existing back-end systems so that relevant information can be provided quickly and easily during the call.
User authentification
A user can be authenticated by requesting data or by voice.
Outbound calls and customer service
Your voicebot can also make outgoing calls or conduct customer satisfaction surveys on its own.
