Python 3.9.4 64位运行pyttsx3报错，寻求技术解决方向

尝试运行语音识别与合成代码，已重装pyttsx、安装pypiwin32并指定安装pyttsx==2.71，仍无法正常运行。

运行代码 #

# Imports
import speech_recognition as sr
import pyttsx3

# Voice Recognition
listener = sr.Recognizer()
speaker = pyttsx3.init()

with sr.Microphone() as input_device:
    print("I am ready")
    voice_content = listener.listen(input_device)
    voice_text = listener.recognize_google(voice_content)
    print(voice_text)

speaker.say("Hello")
speaker.runAndWait()

解决方向 #

• 安装pyobjc依赖：报错显示缺少objc模块，这是macOS系统下pyttsx3依赖的核心模块，执行命令：pip install pyobjc
• 手动指定驱动：若安装后仍报错，修改初始化代码为speaker = pyttsx3.init(driverName='nsss')，确保系统使用NSSpeechSynthesizer驱动
• 检查Python版本兼容性：pyttsx3对Python3.9的支持可能存在兼容问题，可尝试切换到Python3.8或3.10版本测试
• 重新安装最新版pyttsx3：卸载现有版本后安装最新版，执行命令：pip uninstall pyttsx3 && pip install pyttsx3，避免旧版本2.71带来的兼容问题
