Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| synthesize_speechA | Convert text to spoken audio using a real-time, streaming Kokoro-82M TTS gateway. Returns a playable WAV file. The gateway currently runs on an unauthenticated CPU fallback (multi-second latency) — no API key required, but expect a few seconds per call. |

Scored across 1 tool
With only one tool, there is no possibility of overlap or confusion. synthesize_speech clearly indicates its single purpose of converting text to audio.
The tool name follows a clear verb_noun pattern and directly matches the server's TTS purpose. There are no conflicting naming conventions to assess.
A single tool is reasonable for a narrowly scoped TTS server, but the surface feels thin because related capabilities like voice selection or streaming control are absent.
The core text-to-speech operation is covered, but the toolset lacks visible voice, format, or streaming options that would be expected in a realtime TTS service. It works for basic synthesis but leaves notable gaps.
