Deepgram

Turning a stack of call recordings into searchable text is the kind of job Deepgram handles through an API.

Deepgram is a voice AI platform that gives developers speech-to-text, text-to-speech and voice agent APIs in one place.

The same account can also generate spoken audio with human-like voices, so you can build both sides of a voice product without stitching vendors together.

Deepgram runs on optimized GPU infrastructure and positions itself as a cost-effective option for transcription at volume.

Pricing is enterprise-oriented and can get complicated as usage grows, so expect to model your costs before committing.

Self-hosted deployment is possible but may need real technical expertise, and some advanced features need extra configuration.

It works for teams with engineers on hand.
