Rasa-integration for the VIER Cognitive Voice Gateway

Rasa and VIER Cognitive Voice Gateway

Rasa is the leading open-source conversational AI platform that enables both individual developers and large enterprises to build superior AI assistants and chatbots. Rasa provides the infrastructure and tools needed to build the outstanding tools and transform the way customers communicate with businesses. Rasa can be deeply customized down to levels not possible with other platforms due to the open sourced architecture and machine learning.

Rasa is used by millions of developers and small teams to program enterprise conversational AI applications.

VIER Cognitive Voice Gateway (CVG) enables access to telephony, speech-to-text (STT), text-to-speech (TTS) and contact center integration for chatbots built with Rasa. I.e. CVG makes your chatbot to a voicebot handling phone calls.
