PipesHub Conversational Speech API is one of 51 APIs that [PipesHub](https://apis.io/providers/pipeshub/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. This API exposes 6 JSON Schema definitions. Tagged areas include Conversational Speech. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and 6 JSON Schemas.

Server-backed Speech-to-Text (STT) and Text-to-Speech (TTS) for the chat UI. These endpoints are used by the chat frontend when an admin has configured a TTS/STT provider under the AI Models configuration. When no provider is configured the client falls back to the browser's native Web Speech API, so callers should treat a `409` response as "unconfigured, use browser APIs" rather than as a fatal error.
