Returns every speech-to-text transcription engine DialNexa supports. Each entry includes the transcriber’s stable id, the upstream provider (for example Deepgram, AssemblyAI, OpenAI Whisper), the display name, and any configuration metadata the engine exposes. Use this endpoint as the source of truth when configuring an agent’s transcription settings, the transcriber you choose determines how accurately the agent understands what the caller says, which is especially important for accented speech, technical terminology, and non-English languages.

When to use this

• Agent build UIs: populate the transcriber selector when creating or editing an agent.
• Latency tuning: choose between streaming transcribers (lowest first-word latency) and batch transcribers (best accuracy on noisy audio).
• Language coverage checks: confirm the transcriber supports the language an agent is configured for.
• Cost optimization: switch high-volume use cases to lower-cost engines when accuracy budget allows.

For a single record, use Get Transcriber.
