希望支持32000采样率 同 32000hz 因为TTS server 他只能32000hz低了话会有变音问题

Start by searching the Java codebase for text-to-speech handling and audio sample-rate configuration. Verify where the requested 32000 Hz rate is selected, confirm that the TTS server accepts it, and compare the resulting voice output to determine whether the pitch distortion is resolved.
