前言

大家好，我是空空star，本篇給大家分享一下通過Python的pyttsx3庫將文字轉為音頻。

一、pyttsx3是什么？

pyttsx3是一個開源的Python文本轉語音庫，可以將文本轉換為自然的人類語音。它提供了豐富靈活的配置選項，可以自定義聲音，語速，語調等等，并且支持多語言轉換。此外，它還支持異步操作，可以在后臺自動調用語音合成引擎，不會阻塞主程序。Pyttsx3可以廣泛應用于各種領域，例如自動化語音提示、智能語音助手、語音驗證等等，是一個非常優(yōu)秀的Python語音處理庫。

二、安裝pyttsx3

pip install pyttsx3

三、查看pyttsx3版本

 pip show pyttsx3

Name: pyttsx3
Version: 2.90
Summary: Text to Speech (TTS) library for Python 2 and 3. Works without internet connection or delay. Supports multiple TTS engines, including Sapi5, nsss, and espeak.
Home-page: https://github.com/nateshmbhat/pyttsx3

四、pyttsx3的使用

1.引入庫

import pyttsx3

2.定義需要轉換的文本

text = '大家好，我是空空star，本篇給大家分享一下文字轉音頻，這是通過pyttsx3轉換的音頻。'

3.初始化pyttsx3引擎

engine = pyttsx3.init()

4.設置聲音

# 獲取所有可用的聲音列表
voices = engine.getProperty('voices')
# 選擇一個指定語音(粵語語音sinji)
engine.setProperty('voice', voices[36].id)

這里我用的是mac系統(tǒng)下的粵語語音
com.apple.speech.synthesis.voice.sinji

5.設置語速

engine.setProperty('rate', 150)

6.設置音量

engine.setProperty('volume', 0.8)

7.播放語音

engine.say(text)

8.保存語音

local = '/Users/kkstar/Downloads/video/'
engine.save_to_file(text, local+"audio_pyttsx3.mp3")

9.等待完成語言轉換

engine.runAndWait()

engine.runAndWait() 用于在文本轉語音時，等待文本轉換完成后再繼續(xù)程序的執(zhí)行。它的目的是在文本轉換為語音時，避免出現(xiàn)程序過早結束，導致文本無法全部轉換的情況。

五、語音效果

由于博客中不能插入mp3文件，所以先將其轉為mp4，大家通過mp4的聲音來聽轉換效果。
