如何封装一个带传参的python程序成可执行文件
需要使用pydub和SpeechRecognition两个module来实现将m4a声音文件转成文字的python程序。具体实现步骤如下:
1. 安装pydub和SpeechRecognition module
```python
pip install pydub
pip install SpeechRecognition
```
2. 导入module
```python
from pydub import AudioSegment
import os
import speech_recognition as sr
```
3. 使用pydub将m4a文件转换为wav格式
```python
sound = AudioSegment.from_file("example.m4a", format="m4a")
sound.export("example.wav", format="wav")
```
4. 使用SpeechRecognition进行语音识别
```python
r = sr.Recognizer()
with sr.AudioFile("example.wav") as source:
audio = r.record(source)
text = r.recognize_google(audio)
print(text)
```
完整代码如下:
```python
from pydub import AudioSegment
import os
import speech_recognition as sr
sound = AudioSegment.from_file("example.m4a", format="m4a")
sound.export("example.wav", format="wav")
r = sr.Recognizer()
with sr.AudioFile("example.wav") as source:
audio = r.record(source)
text = r.recognize_google(audio)
print(text)
```
需要注意的是,这个程序需要保证m4a文件和python程序在同一个文件夹下,并且在语音识别时需要联网。
