Python文本转语音引擎pyttsx3的使用完全指南

pip install pyttsx3

pip install pyobjc

sudo apt-get install espeak

import pyttsx3

# 初始化TTS引擎
engine = pyttsx3.init()

# 设置要说的文本
engine.say("你好，我是Python文本转语音引擎")

# 运行并等待语音完成
engine.runAndWait()

# 获取当前语速
rate = engine.getProperty('rate')
print(f"当前语速：{rate}")

# 设置新的语速 (降低50%)
engine.setProperty('rate', rate-100)

engine.say("这是降低语速后的语音效果")
engine.runAndWait()

# 获取当前音量
volume = engine.getProperty('volume')
print(f"当前音量：{volume}")

# 设置新的音量 (0.0 到 1.0)
engine.setProperty('volume', 0.7)  # 70%音量

engine.say("这是调整音量后的语音效果")
engine.runAndWait()

# 获取可用声音的列表
voices = engine.getProperty('voices')

# 打印可用声音的信息
for i, voice in enumerate(voices):
    print(f"语音{i}:")
    print(f" - ID: {voice.id}")

    print(f" - 语言: {voice.languages}")

# 设置第二个声音（如果有的话）
if len(voices) > 1:
    engine.setProperty('voice', voices[1].id)
    engine.say("这是使用另一个声音的效果")
    engine.runAndWait()

engine = pyttsx3.init()

# 设置要保存的文本

# 保存为WAV文件
engine.save_to_file(text, 'output.wav')
