URL	`wss://ws.coze.cn/v1/audio/speech`
Headers	`Authorization Bearer` `$Access_Token` 用于验证客户端身份的访问令牌。你可以在扣子编程中生成访问令牌，详细信息请参考准备工作。
权限	`createSpeech`
接口说明	将文字信息转为指定音色的语音片段。

限制说明

单次请求的文字信息长度最大为 1024 个字节。超过上限时会提示 3010 错误。
建议一次性不要传输太多文字。

建连示例代码

import WebSocket from 'ws';

const url = `wss://ws.coze.cn/v1/audio/speech?authorization=Bearer ${ACCESS_TOKEN}`;
const ws = new WebSocket(url);

ws.on('open', function open() {
  console.log('Connected to server.');
});

ws.on('message', function incoming(message) {
  console.log(JSON.parse(message.toString()));
});

# example requires websocket-client library:
# pip install websocket-client

import os
import json
import websocket

ACCESS_TOKEN = os.environ.get("ACCESS_TOKEN")

url = "wss://ws.coze.cn/v1/audio/speech"

headers = [
    "Authorization: Bearer " + ACCESS_TOKEN
]

def on_open(ws):
    print("Connected to server.")

def on_message(ws, message):
    data = json.loads(message)
    print("Received event:", json.dumps(data, indent=2))

ws = websocket.WebSocketApp(
    url,
    header=headers,
    on_open=on_open,
    on_message=on_message,
)

ws.run_forever()

const url = `wss://ws.coze.cn/v1/audio/speech?authorization=Bearer ${ACCESS_TOKEN}`;
const ws = new WebSocket(url);

ws.addEventListener('open', function () {
  console.log('Connected to server.');
});

ws.addEventListener('message', function (message) {
  console.log(JSON.parse(message.data.toString()));
});
