Wav to Txt 聲音檔案轉換成純文字檔 (逐字稿)

 情境:逐字稿 公司提供開完會後之WAV錄音檔，想轉換成「純文字檔」,節省打字時間

需預先載入:語音辨識相關套件

pip install SpeechRecognition


以下為PYTHON程式:

import os,sys
import subprocess


import speech_recognition as sr

# language='ja-JP' 可改成辨識日文語系; language='en-US' 可改成辨識英文語系
def convert_audio_to_text(audio_file):
    recognizer = sr.Recognizer()
    with sr.AudioFile(audio_file) as source:
        audio = recognizer.record(source)
    try:
        text = recognizer.recognize_google(audio, language='zh-TW')
        return text
    except sr.UnknownValueError:
        return "無法辨識音訊"
    except sr.RequestError:
        return "無法連接到語音識別服務"


#'開啟GUI 取得來源檔(準備欲轉換聲音來源,開啟檔案對話視窗宣告處理)
import tkinter as tk
from tkinter import filedialog

root = tk.Tk()
root.withdraw()

# 取得轉換聲音,轉成純文字檔來源資訊
file_path = filedialog.askopenfilename(initialdir = "/",title = "Select file for OCR (選擇欲辨識聲音檔轉文字檔)",filetypes = (("Audio files","*.wav"),("All files","*.*")))

text1 = convert_audio_to_text(file_path)
print(text1)

with open('wavfile.txt', mode = 'w') as f:
    f.write(text1)
    f.close()

#將剛產出之文字檔,直接開啟顯示出來

subprocess.Popen('explorer "wavfile.txt"')
