Dial
Options for dialing a Voice Relay endpoint through the Sinch Voice V2 platform.
Voice Relay connects the call to speech-to-text (STT) and text-to-speech (TTS) services through a WebSocket endpoint. A null optional property is omitted from the dial request and the Voice V2 platform applies its default.
See Voice locales for the available voices and locales.
