以下是一个使用Python实现简单前端UI交互，可进行语音录入实现声纹注册与识别功能的代码示例。这里使用`tkinter`作为前端UI库，`pyaudio`进行语音录入，`librosa`提取音频特征，`sklearn`的`GaussianMixture`作为声纹识别模型。 ```python import tkinter as tk from tkinter import messagebox import pyaudio import wave import librosa import numpy as np from sklearn.mixture import GaussianMixture # 提取音频特征 def extract_features(audio_path): y, sr = librosa.load(audio_path) mfccs = librosa.feature.mfcc(y=y, sr=sr, n_mfcc=13) return mfccs.T # 训练GMM模型 def train_gmm(features): gmm = GaussianMixture(n_components=16, covariance_type='diag') gmm.fit(features) return gmm # 测试声纹 def test_gmm(gmm, test_features): scores = gmm.score(test_features) return scores # 录音函数 def record_audio(filename, duration=5): CHUNK = 1024 FORMAT = pyaudio.paInt16 CHANNELS = 1 RATE = 44100 p = pyaudio.PyAudio() stream = p.open(format=FORMAT, channels=CHANNELS, rate=RATE, input=True, frames_per_buffer=CHUNK) frames = [] for i in range(0, int(RATE / CHUNK * duration)): data = stream.read(CHUNK) frames.append(data) stream.stop_stream() stream.close() p.terminate() wf = wave.open(filename, 'wb') wf.setnchannels(CHANNELS) wf.setsampwidth(p.get_sample_size(FORMAT)) wf.setframerate(RATE) wf.writeframes(b''.join(frames)) wf.close() # 声纹注册 def register_voice(): record_audio('registered_voice.wav') features = extract_features('registered_voice.wav') global gmm_model gmm_model = train_gmm(features) messagebox.showinfo("注册成功", "声纹注册成功！") # 声纹识别 def recognize_voice(): if 'gmm_model' not in globals(): messagebox.showerror("错误", "请先注册声纹！") return record_audio('test_voice.wav') test_features = extract_features('test_voice.wav') score = test_gmm(gmm_model, test_features) if score > -1000: # 这里的阈值可以根据实际情况调整 messagebox.showinfo("识别成功", "声纹识别成功！") else: messagebox.showerror("识别失败", "声纹识别失败！") # 创建主窗口 root = tk.Tk() root.title("声纹注册与识别") # 创建按钮 register_button = tk.Button(root, text="注册声纹", command=register_voice) register_button.pack(pady=20) recognize_button = tk.Button(root, text="声纹识别", command=recognize_voice) recognize_button.pack(pady=20) # 运行主循环 root.mainloop() ```
