从入门到实战详解Python文本转语音的完全指南

# 创建虚拟环境
python -m venv tts_env
# 激活环境
# Windows:
tts_env\Scripts\activate
# Mac/Linux:
source tts_env/bin/activate

pip install pyttsx3
# 如果需要更好的兼容性，安装特定版本
pip install pyttsx3==2.90

pip install pypiwin32

import pyttsx3

engine = pyttsx3.init()
engine.say("你好，世界！Hello World!")
engine.runAndWait()

import pyttsx3

engine = pyttsx3.init()

# 获取当前语速
rate = engine.getProperty('rate')
print(f"当前语速: {rate}")  # 默认 200

# 设置语速（范围 50-300）
engine.setProperty('rate', 150)  # 变慢
engine.say("这是慢速语音")
engine.runAndWait()

import pyttsx3

engine = pyttsx3.init()

# 获取当前音量
volume = engine.getProperty('volume')
print(f"当前音量: {volume}")  # 默认 1.0

# 设置音量（范围 0.0 - 1.0）
engine.setProperty('volume', 0.8)  # 80% 音量
engine.say("这是80%音量的语音")
engine.runAndWait()

import pyttsx3

engine = pyttsx3.init()

# 查看所有可用语音
voices = engine.getProperty('voices')
for i, voice in enumerate(voices):
    print(f"语音 {i}: {voice.name} (ID: {voice.id})")

# 切换到中文语音（通常是索引 1）
engine.setProperty('voice', voices[1].id)
engine.say("这是中文语音")
engine.runAndWait()

# 切换到英文语音（通常是索引 0）
engine.setProperty('voice', voices[0].id)
engine.say("This is English voice")
engine.runAndWait()

import pyttsx3

engine = pyttsx3.init()

# 设置保存路径
engine.save_to_file("你好，这是保存的音频", "test.mp3")
engine.runAndWait()

print("✅ 音频已保存为 test.mp3")

# 方案A：升级 Python 到 3.8+
# 方案B：降级 pyttsx3
pip install pyttsx3==2.90

import pyttsx3

engine = pyttsx3.init()

# 🔑 关键：手动设置语音
voices = engine.getProperty('voices')
engine.setProperty('voice', voices[0].id)  # 使用第一个语音

engine.say("测试成功")
engine.runAndWait()
