3. API接口详解
VibeVoice提供了两种主要的API接口方式:RESTful配置查询和WebSocket流式合成。下面我们详细讲解每种接口的使用方法。
3.1 获取配置信息接口
在开始语音合成前,通常需要先获取可用的音色列表和默认配置。
接口地址:GET http://localhost:7860/config
使用示例:
curl http://localhost:7860/config响应示例:
{ "voices": [ "en-Carter_man", "en-Davis_man", "en-Emma_woman", "en-Frank_man", "en-Grace_woman", "en-Mike_man", "in-Samuel_man", "de-Spk0_man", "fr-Spk0_man", "jp-Spk0_man" ], "default_voice": "en-Carter_man", "default_cfg": 1.5, "default_steps": 5 }编程语言调用示例:
Python示例:
import requests def get_vibevoice_config(host='localhost', port=7860): """获取VibeVoice配置信息""" url = f"http://{host}:{port}/config" try: response = requests.get(url, timeout=10) response.raise_for_status() return response.json() except requests.exceptions.RequestException as e: print(f"获取配置失败: {e}") return None # 使用示例 config = get_vibevoice_config() if config: print("可用音色:", config['voices']) print("默认音色:", config['default_voice'])JavaScript示例:
async function getVibeVoiceConfig(host = 'localhost', port = 7860) { try { const response = await fetch(`http://${host}:${port}/config`); if (!response.ok) { throw new Error(`HTTP error! status: ${response.status}`); } const config = await response.json(); console.log('可用音色:', config.voices); console.log('默认音色:', config.default_voice); return config; } catch (error) { console.error('获取配置失败:', error); return null; } }3.2 WebSocket流式合成接口
这是VibeVoice的核心接口,支持实时流式语音合成,能够实现边生成边播放的效果。
接口地址:ws://localhost:7860/stream
请求参数:
text:要合成的文本内容(必需)voice:音色名称(可选,默认为en-Carter_man)cfg:CFG强度参数(可选,默认1.5,范围1.3-3.0)steps:推理步数(可选,默认5,范围5-20)
WebSocket URL示例:
ws://localhost:7860/stream?text=Hello%20World&voice=en-Emma_woman&cfg=1.5&steps=54. 实战集成示例
下面通过几个具体示例,展示如何在不同编程语言中集成VibeVoice API。
4.1 Python集成示例
基础WebSocket客户端:
import asyncio import websockets import json import wave class VibeVoiceClient: def __init__(self, host='localhost', port=7860): self.ws_url = f"ws://{host}:{port}/stream" async def synthesize_speech(self, text, voice=None, cfg=1.5, steps=5, output_file=None): """合成语音并保存到文件""" # 构建查询参数 params = f"text={text}&cfg={cfg}&steps={steps}" if voice: params += f"&voice={voice}" try: async with websockets.connect(f"{self.ws_url}?{params}") as websocket: audio_data = bytearray() # 接收音频数据 async for message in websocket: if isinstance(message, bytes): audio_data.extend(message) # 保存为WAV文件 if output_file and audio_data: with wave.open(output_file, 'wb') as wav_file: wav_file.setnchannels(1) # 单声道 wav_file.setsampwidth(2) # 16位 wav_file.setframerate(24000) # 24kHz采样率 wav_file.writeframes(audio_data) print(f"音频已保存到: {output_file}") return True except Exception as e: print(f"语音合成失败: {e}") return False # 使用示例 async def main(): client = VibeVoiceClient() # 合成英文语音 await client.synthesize_speech( text="Hello, welcome to use VibeVoice API!", voice="en-Emma_woman", output_file="output.wav" ) # 运行 if __name__ == "__main__": asyncio.run(main())实时流式播放示例:
import pyaudio import asyncio import websockets class RealTimeVibeVoice: def __init__(self, host='localhost', port=7860): self.ws_url = f"ws://{host}:{port}/stream" self.audio = pyaudio.PyAudio() self.stream = self.audio.open( format=pyaudio.paInt16, channels=1, rate=24000, output=True ) async def stream_speech(self, text, voice=None, cfg=1.5, steps=5): """实时流式播放语音""" params = f"text={text}&cfg={cfg}&steps={steps}" if voice: params += f"&voice={voice}" try: async with websockets.connect(f"{self.ws_url}?{params}") as websocket: print("开始实时语音合成...") async for audio_chunk in websocket: if isinstance(audio_chunk, bytes): self.stream.write(audio_chunk) print("语音合成完成") except Exception as e: print(f"实时合成失败: {e}") finally: self.stream.stop_stream() self.stream.close() self.audio.terminate() # 使用示例 async def real_time_demo(): tts = RealTimeVibeVoice() await tts.stream_speech( text="This is real-time speech synthesis with VibeVoice!", voice="en-Carter_man" )4.2 JavaScript/Node.js集成示例
Node.js WebSocket客户端:
const WebSocket = require('ws'); const fs = require('fs'); class VibeVoiceNodeClient { constructor(host = 'localhost', port = 7860) { this.baseUrl = `ws://${host}:${port}/stream`; } /** * 合成语音并保存到文件 */ async synthesizeSpeech(text, options = {}) { const { voice = 'en-Carter_man', cfg = 1.5, steps = 5, outputFile = 'output.wav' } = options; const params = new URLSearchParams({ text: text, cfg: cfg, steps: steps, voice: voice }); return new Promise((resolve, reject) => { const ws = new WebSocket(`${this.baseUrl}?${params}`); const audioChunks = []; ws.on('message', (data) => { if (Buffer.isBuffer(data)) { audioChunks.push(data); } }); ws.on('close', () => { if (audioChunks.length > 0) { const audioBuffer = Buffer.concat(audioChunks); // 创建WAV文件头 const wavHeader = this.createWavHeader(audioBuffer.length); const fullBuffer = Buffer.concat([wavHeader, audioBuffer]); fs.writeFile(outputFile, fullBuffer, (err) => { if (err) { reject(err); } else { console.log(`音频已保存到: ${outputFile}`); resolve(outputFile); } }); } else { reject(new Error('未接收到音频数据')); } }); ws.on('error', reject); }); } /** * 创建WAV文件头 */ createWavHeader(dataLength) { const buffer = Buffer.alloc(44); const sampleRate = 24000; const numChannels = 1; const bitsPerSample = 16; const byteRate = sampleRate * numChannels * bitsPerSample / 8; const blockAlign = numChannels * bitsPerSample / 8; // RIFF头 buffer.write('RIFF', 0); buffer.writeUInt32LE(36 + dataLength, 4); buffer.write('WAVE', 8); // fmt子块 buffer.write('fmt ', 12); buffer.writeUInt32LE(16, 16); // fmt块大小 buffer.writeUInt16LE(1, 20); // PCM格式 buffer.writeUInt16LE(numChannels, 22); buffer.writeUInt32LE(sampleRate, 24); buffer.writeUInt32LE(byteRate, 28); buffer.writeUInt16LE(blockAlign, 32); buffer.writeUInt16LE(bitsPerSample, 34); // data子块 buffer.write('data', 36); buffer.writeUInt32LE(dataLength, 40); return buffer; } } // 使用示例 async function demo() { const client = new VibeVoiceNodeClient(); try { await client.synthesizeSpeech( 'Hello from Node.js! This is VibeVoice API integration.', { voice: 'en-Emma_woman', outputFile: 'node_output.wav' } ); } catch (error) { console.error('合成失败:', error); } } demo();4.3 Web前端集成示例

5.1 参数调优指南
VibeVoice提供了两个重要参数用于调整语音质量:
CFG强度(cfg):
- 范围:1.3 - 3.0
- 默认值:1.5
- 较低值(1.3-1.7):生成更自然、更多样化的语音,但可能降低清晰度
- 较高值(2.0-3.0):生成更清晰、更准确的语音,但可能显得机械
推理步数(steps):
- 范围:5 - 20
- 默认值:5
- 较少步数(5-10):生成速度更快,适合实时应用
- 较多步数(15-20):生成质量更高,适合离线处理
推荐配置:
# 实时对话应用(速度优先) params = {"cfg": 1.5, "steps": 5} # 音频内容制作(质量优先) params = {"cfg": 2.0, "steps": 15} # 平衡模式 params = {"cfg": 1.8, "steps": 10}5.2 错误处理与重试机制
在实际应用中,需要添加适当的错误处理和重试机制:
import asyncio from tenacity import retry, stop_after_attempt, wait_exponential class RobustVibeVoiceClient(VibeVoiceClient): @retry(stop=stop_after_attempt(3), wait=wait_exponential(multiplier=1, min=4, max=10)) async def synthesize_with_retry(self, text, **kwargs): """带重试机制的语音合成""" try: return await self.synthesize_speech(text, **kwargs) except websockets.exceptions.ConnectionClosedError: print("连接断开,尝试重连...") raise except Exception as e: print(f"合成失败: {e}") raise async def safe_synthesize(self, text, max_retries=3, **kwargs): """安全的语音合成,带重试和回退""" for attempt in range(max_retries): try: return await self.synthesize_with_retry(text, **kwargs) except Exception as e: if attempt == max_retries - 1: print(f"所有重试失败: {e}") # 可以在这里添加回退方案,如使用其他TTS服务 return False await asyncio.sleep(2 ** attempt) # 指数退避5.3 性能优化建议
连接池管理:
from websockets import connect import asyncio class ConnectionPool: def __init__(self, max_connections=5): self.max_connections = max_connections self.semaphore = asyncio.Semaphore(max_connections) self.connections = [] async def get_connection(self, ws_url): await self.semaphore.acquire() try: ws = await connect(ws_url) self.connections.append(ws) return ws except Exception as e: self.semaphore.release() raise e async def release_connection(self, ws): try: await ws.close() finally: self.connections.remove(ws) self.semaphore.release() # 使用连接池 async def batch_synthesize(texts, voices): pool = ConnectionPool(max_connections=3) tasks = [] for text, voice in zip(texts, voices): task = asyncio.create_task( synthesize_with_pool(pool, text, voice) ) tasks.append(task) results = await asyncio.gather(*tasks, return_exceptions=True) return results async def synthesize_with_pool(pool, text, voice): ws_url = f"ws://localhost:7860/stream?text={text}&voice={voice}" ws = await pool.get_connection(ws_url) try: # 进行语音合成 audio_data = bytearray() async for message in ws: if isinstance(message, bytes): audio_data.extend(message) return audio_data finally: await pool.release_connection(ws)6. 总结
