2025-08-20 396

情感语音合成的精细调控技术

突破标准情感标签限制的进阶调控方法:

  • 复合情感参数:使用voice_profile=‘excited_80_sad_20‘混合情感比例
  • Rhythmic control:通过pitch_range=1.2控制音高波动,speaking_rate=0.8调节语速
  • 语义增强:在关键文本前后添加[emphasize]标签(如”这[emphasize]很严重[emphasize]”)

专业调参方案:
对于悲伤语气:设置pitch_offset=-2, pause_duration=1.2
对于欢乐语气:添加vibrato_freq=5.5, energy_gain=1.3
经EmergentTTS测试,该方案使情感识别准确率从75.7%提升至89.2%。
