The dashboard’s voice controls are unsaved previews, and voice publication is unavailable. Language-specific voice references do not establish multi-speaker output or voice switching during a live conversation.
Prepare voice references
You need a target branch and saved voices that your workspace can access. Start with List my voices and the current model catalog.1
Choose the default pair
Set
conversation_config.tts.model_id and conversation_config.tts.voice_id. Record the selected model, voice, and intended base language together.2
Choose a voice for each additional language
In
conversation_config.language_presets, use the language tag as the map key. A preset can set overrides.tts.voice_id to an accessible saved voice.The preset does not contain a replacement TTS model. Review each voice against the base TTS model and that language’s requirements.3
Keep the wording consistent
Review each language’s first message and pronunciation requirements. A voice reference does not translate the prompt or establish that a voice supports every language.

Inspect the saved draft
Follow versions and drafts. Read the draft back to confirm the default voice and each language-specific reference. Do not use publication as a voice test while voice publication is gated.
Choose voices deliberately
Keep the selection small enough to review. For each voice, record the intended language, character of delivery, and a short sample script with names and numbers. These are preparation materials for later listening tests, not evidence that conversation switching is working. If a voice is inaccessible, check the active workspace and saved identifier before changing the rest of the configuration.Frequently asked questions
