librosa安装

2024.04.27 测试ok Win11系统

pip install librosa

import os
 
import numpy as np
from transformers import Wav2Vec2Processor, Wav2Vec2Model
import torch
 
import librosa
 
 
def load_example_input(audio_path, processor=None):
    if processor is None:
        processor = Wav2Vec2Processor.from_pretrained("facebook/wav2vec2-base-960h")
 
    speech_array, sampling_rate = librosa.load(os.path.join(audio_path), sr=16000)
 
    audio_feature = np.squeeze(processor(speech_array, sampling_rate=sampling_rate).input_values)
 
    audio_feature = np.reshape(audio_feature, (-1, audio_feature.shape[0]))
 
    return torch.FloatTensor(audio_feature)
 
 
audio_path=r'demo/wav/man.wav'
 
 
load_example_input(audio_path)

语音识别

pip install SpeechRecognition

pip install pyaudio

import librosa
import speech_recognition as sr
 
# 录制音频
r = sr.Recognizer()
with sr.Microphone() as source:
    print("请开始说话...")
    audio = r.listen(source)
 
# 将音频转换为文本
try:
    text = r.recognize_google(audio)
    print("识别结果：", text)
except sr.UnknownValueError:
    print("无法识别音频")
except sr.RequestError as e:
    print(f"请求出错：{e}")
