17
+ - 🤖 **智能对话生成** - 支持多种大语言模型(Qwen、Llama、Mistral等)
18
+ - 🔊 **高质量语音合成** - 基于 GPT-SoVITS 的多角色语音生成
19
+ - 🔇 **回声消除** - 内置音频处理,支持实时语音交互
20
+ - 🌍 **多语言支持** - 支持中文和英文语音识别与合成
21
+
22
+ ## ✨ 主要特性
23
+
24
+ ### 🎵 音频处理
25
+ - **回声消除音频捕获** - 消除回声干扰,提升语音质量
26
+ - **语音活动检测** - 自动检测用户说话状态
27
+ - **实时音频流处理** - 低延迟音频播放
28
+
29
+ ### 🗣️ 语音识别
30
+ - **Whisper 模型支持** - Medium/Large 模型可选
31
+ - **多语言识别** - 支持中文/英文自动识别
32
+ - **实时转录** - 流式语音转文本处理
33
+
34
+ ### 🧠 语言模型
35
+ 支持多种预训练模型:
36
+ - **Qwen2.5** (7B/14B) - 中文优化模型
37
+ - **Llama3** (8B) - 通用对话模型
38
+ - **Mistral** (7B) - 高效推理模型
39
+ - **Phi-3** (mini) - 轻量级模型
40
+
41
+ ### 🎭 语音合成
42
+ 内置多种音色选择:
43
+ - 罗翔 - 法学教授风格
44
+ - 马保国 - 网络名人风格
45
+ - 沈逸 - 学者风格
46
+ - 杨幂 - 明星风格
47
+ - 周杰伦 - 歌手风格
48
+ - 马云 - 企业家风格
49
+
50
+ ## 🚀 快速开始
51
+
52
+ ### 环境要求
53
+
54
+ - Python 3.9+
55
+ - macOS 14+
56
+
57
+ ### 安装步骤
58
+
59
+ 1. **克隆项目**
60
+ ```bash
61
+ git clone https://huggingface.co/MoYoYoTech/VoiceDialogue
62
+ cd VoiceDialogue
63
+ ```
64
+
65
+ 2. **创建虚拟环境**
66
+ ```bash
67
+ conda create -n voicedialogue python=3.9
68
+ conda activate voicedialogue
69
+ ```
70
+
71
+ 3. **安装依赖**
72
+ ```bash
73
+ # 基础依赖
74
+ pip install torch torchaudio --index-url https://download.pytorch.org/whl/cu118
75
+ pip install -r requirements.txt
76
+
77
+ # 音频处理
78
+ conda install ffmpeg
79
+
80
+ # macOS 额外依赖
81
+ brew install ffmpeg # macOS only
82
+ ```
83
+
84
+ 4. **下载模型文件**
85
+
86
+ 模型会在首次运行时自动下载,或手动下载:
87
+
88
+ ```bash
89
+ # ASR 模型 (Whisper)
90
+ mkdir -p models/asr
91
+ # 下载 whisper 模型到 models/asr/
92
+
93
+ # LLM 模型
94
+ mkdir -p models/llm
95
+ # 模型将从 HuggingFace 自动下载
96
+
97
+ # TTS 模型
98
+ mkdir -p models/tts
99
+ # GPT-SoVITS 模型将自动下载
100
+ ```
101
+
102
+ ### 🎮 运行程序
103
+
104
+ ```bash
105
+ # 启动语音对话系统
106
+ python -m src.VoiceDialogue.main
107
+ ```
108
+
109
+ ### ⚙️ 配置选项
110
+
111
+ 在 `src/VoiceDialogue/main.py` 中可以自定义:
112
+
113
+ ```python
114
+ def main():
115
+ # 语言设置
116
+ user_language = 'zh' # 'zh' 中文 | 'en' 英文
117
+
118
+ # 系统提示词
119
+ SYSTEM_PROMPT = "你是善于模拟真实思考过程的AI助手..."
120
+
121
+ # TTS 音色选择
122
+ tts_speaker = '沈逸' # 可选: 罗翔、马保国、沈逸、杨幂、周杰伦、马云
123
+
124
+ # LLM 模型大小
125
+ llm = '14B' # '7B' | '14B'
126
+
127
+ # Whisper 模型
128
+ whisper_model = 'medium' # 'medium' | 'large'
129
+ ```

+ # AECAudioStream
2
+
3
+ ## 概述
4
+ AECAudioStream 是一个用于捕获系统音频输入并应用声学回声消除(AEC)过滤器的 Swift 库。它提供了一个便捷的接口,允许用户捕获音频数据、处理声学回声消除,并支持语音活动检测(VAD)功能。
5
+
6
+ ## 功能特点
7
+ - 音频捕获:从系统音频输入设备捕获音频数据
8
+ - 声学回声消除(AEC):通过内置过滤器消除回声
9
+ - 语音活动检测(VAD):检测是否有语音活动
10
+ - 灵活的音频处理:支持自定义音频处理回调
11
+ - 线程安全的音频数据队列管理
12
+
13
+ ## 系统要求
14
+ - macOS 操作系统
15
+ - Swift 5.0+
16
+
17
+ ## 编译方法
18
+ 使用以下命令编译生成动态库:
19
+ ``` bash
20
+ swiftc -emit-library -o libAudioCapture.dylib AECAudioStream.swift
21
+ ```
22
+ ## 使用方法
23
+ ### 初始化
24
+ ``` swift
25
+ // 创建一个采样率为16000的音频流实例
26
+ let audioStream = AECAudioStream(sampleRate: 16000)
27
+ ```
28
+ ### 启动音频捕获
29
+ ``` swift
30
+ // 启动音频流并启用回声消除
31
+ let audioBufferStream = try audioStream.startAudioStream(enableAEC: true)
32
+
33
+ // 异步处理捕获的音频数据
34
+ Task {
35
+ for try await pcmBuffer in audioBufferStream {
36
+ // 处理音频数据
37
+ processAudioData(pcmBuffer)
38
+ }
39
+ }
40
+ ```
41
+ ### 使用回调方式
42
+ ``` swift
43
+ // 启动音频流并通过回调处理
44
+ try audioStream.startAudioStream(enableAEC: true) { buffer in
45
+ // 通过回调处理音频数据
46
+ }
47
+ ```
48
+ ### 启用语音活动检测(VAD)
49
+ ``` swift
50
+ // 启用VAD功能
51
+ try audioStream.toggleVoiceActivityDetection(enable: true)
52
+
53
+ // 设置VAD状态变化的回调
54
+ audioStream.voiceActivityHandler = { isVoiceDetected in
55
+ if isVoiceDetected {
56
+ print("检测到语音活动")
57
+ } else {
58
+ print("未检测到语音活动")
59
+ }
60
+ }
61
+ ```
62
+ ### 停止音频捕获
63
+ ``` swift
64
+ // 停止音频单元
65
+ try audioStream.stopAudioUnit()
66
+ ```
67
+ ## C 接口
68
+ 库提供了以下 C 接口函数,方便从其他语言调用:
69
+ - `startRecord()`: 开始录音并将音频数据存入队列
70
+ - `stopRecord()`: 停止录音
71
+ - `getAudioData()`: 获取音频数据
72
+ - `freeAudioData()`: 释放音频数据缓冲区
73
+ - `isVoiceActive()`: 获取当前语音活动检测状态
74
+
75
+ ### C 接口使用示例
76
+ ``` c
77
+ // 开始录音
78
+ startRecord();
79
+
80
+ // 获取音频数据
81
+ int size;
82
+ uint8_t* audioData = getAudioData(&size);
83
+ if (audioData != NULL && size > 0) {
84
+ // 处理音频数据
85
+ processAudioData(audioData, size);
86
+
87
+ // 处理完成后释放内存
88
+ freeAudioData(audioData);
89
+ }
90
+
91
+ // 停止录音
92
+ stopRecord();
93
+ ```
94
+ ## 类和组件
95
+ ### AECAudioStream
96
+ 主要类,提供音频捕获和处理功能。
97
+ ### AudioDataQueue
98
+ 线程安全的音频数据队列,用于存储捕获的音频数据。
99
+ ### AECAudioStreamError
100
+ 定义可能抛出的错误类型。
101
+ ## 注意事项
102
+ - 确保在使用完毕后调用 `stopAudioUnit()` 以释放资源
103
+ - 使用 VAD 功能时需要适当的权限
104
+ - 使用 C 接口获取音频数据后,必须调用 `freeAudioData()` 释放内存
