MultiTrack Call Transcription with Split Recording

Nexmo has improved its call recording capabilities by supporting up to 32 channels in every single recording, making it easier to handle common use cases such as transcription for multi-participant calls. To achieve this, developers can create a Node.js application that uses Nexmo's Voice API to connect multiple participants and record their conversations. The application must handle HTTP requests from Nexmo, including webhook notifications when recordings are available, and transcribe the audio using Google's Speech-To-Text service. With this setup, developers can automatically transcribe multi-participant calls, including separate channels for each participant, allowing them to accurately identify who said what during the conversation.
