常用示例

说明

say converts text to audible speech using the macOS Speech Synthesis manager. It speaks text provided as arguments, from a file, or from standard input, either through audio output or saved to a file. Multiple voices are available with different accents, languages, and personalities. The default voice and speech settings can be configured in System Settings under Accessibility > Spoken Content. Output can be saved to AIFF, WAVE, m4af, or caff audio formats for later playback or processing.
