Name Type Description
provider string
model string The Soniox model to use for transcription.
language string Single language for transcription as an ISO 639-1 code (e.g., `en`, `es`). For multi-language hints or to enable Soniox auto-detect, use `languages` instead — when `languages` is set (including to an
languages string Language hints sent to Soniox as `language_hints`. Provide `[lang1, lang2, ...]` (ISO 639-1 codes) to bias recognition toward specific languages, or provide an explicit empty array `[]` to enable Soni
languageHintsStrict boolean When `true`, Soniox strictly restricts transcription to the languages in `languages` (or the singular `language` if `languages` is unset). When `false`, Soniox biases toward those languages but still
maxEndpointDelayMs number Maximum delay in milliseconds between when the speaker stops and when the endpoint is detected. Lower values mean faster turn-taking but more false endpoints. Range: 500-3000. Default: 500.
customVocabulary array Custom vocabulary terms to boost recognition accuracy. Useful for brand names, product names, and domain-specific terminology. Maps to Soniox context.terms.
contextGeneral array General context key-value pairs that guide the AI model during transcription. Helps adapt vocabulary to the correct domain, improving accuracy. Recommended: 10 or fewer pairs. Maps to Soniox context.g
fallbackPlan object This is the plan for transcriber provider fallbacks in the event that the primary transcriber provider fails.
