Deepgram
Deepgram provides speech-to-text, conversation-aware Flux text-to-speech (TTS), and a Voice Agent API for real-time and batch voice applications. You send audio or text; Deepgram returns transcripts, context-aware TTS that handles interruptions, and APIs deployable in cloud, VPC or on-prem environments for regulated workloads.
The linked official pages document a limited-time free Flux TTS developer option and invite users to "See pricing" or talk to sales, but do not list persistent plan prices on the linked official pages.Is Deepgram right for you?
Good for
- Teams building conversational voice agents that need cross-turn context, interruption handling, and flexible deployment (cloud, VPC, or on-prem).
- Conversation-aware TTS that carries context and handles interruptions across turns.
- Deployable where data must live: cloud, VPC, or on-prem for data residency and regulated workloads.
Keep in mind
- The free Flux TTS developer offering is explicitly time-limited and reverts to standard pricing after the promotional period.
- linked official pages show prompts to "See pricing" and contact sales but do not list ongoing per-unit or subscription prices.
- Confirm ongoing per-unit pricing and concurrency limits before committing, because the linked official pages show promotional free Flux access but do not list persistent plan prices in the available information.
Pricing and plan limits
