# Examples - [agent-profile.json](agent-profile.json) is an illustrative agent-profile response with a dynamic tool catalog. Its model instructions are written in English and request Spanish speech through both instructions and `language`. Tool names and schemas illustrate the original API response; this file is not loaded by the application and is not a live API contract. - [reference-audio.wav](reference-audio.wav) is the existing optional voice-cloning sample, moved out of the implementation directory. CustomVoice models do not require it. When testing a compatible Base/voice-cloning model, supply its path explicitly with `--qwen3_tts_ref_audio docs/examples/reference-audio.wav` from the project root and use the matching transcription required by that model. See [the TTS guide](../speech/tts.md). These examples contain no deployment credentials and are not default runtime configuration. Use an authorized reference voice for your own deployment.
