Integrate Deepgram with Vonage AI Studio for Speech Recognition

This article discusses integrating an external Automatic Speech Recognition (ASR) engine with Vonage AI Studio to enhance the functionality of voice-driven applications. The integration uses the Deepgram ASR Engine service provider, which offers more control over accuracy, transcription speed, and custom vocabulary compared to the built-in ASR solution in Vonage AI Studio. The article guides readers through setting up the integration by creating a Deepgram project, retrieving an API key, and linking a phone number to the application. It also provides instructions on how to set up the HTTP Agent, run the ASR application locally, test the sample AI Agent and ASR Connector, and troubleshoot potential issues. The integration enables efficient handling of PSTN-type calls and can be extended to support additional communication channels, such as SIP calls or WebRTC clients.
