讯飞提供了一系列的语音识别API,其中包括实时语音识别。你可以使用Python来调用讯飞提供的API,实现实时语音识别的功能。下面是一个简单的示例代码:
```python
import websocket
import datetime
import hashlib
import base64
import json
# 设置讯飞API的相关参数
APPID = 'your_appid'
API_KEY = 'your_api_key'
API_SECRET = 'your_api_secret'
# 获取当前时间戳
now = datetime.datetime.now()
timestamp = str(int(now.timestamp()))
# 构造签名信息
signature_origin = f"{API_KEY}POSThttps://iat-api.xfyun.cn/v2/iatrealtime{timestamp}content-type:application/json"
signature_sha = hashlib.sha256(signature_origin.encode('utf-8')).digest()
signature = base64.b64encode(signature_sha).decode('utf-8')
# 构造websocket连接地址
url = f'wss://iat-api.xfyun.cn/v2/iatrealtime?authorization={API_KEY}:{signature}&date={timestamp}&host=iat-api.xfyun.cn'
# 发送websocket请求
def on_message(ws, message):
result = json.loads(message)
if result['code'] == 0:
print(result['data']['result'])
def on_error(ws, error):
print(error)
def on_close(ws):
print("### closed ###")
def on_open(ws):
def run(*args):
# 发送开始识别命令
data = {
"common": {
"app_id": APPID
},
"business": {
"language": "zh_cn",
"domain": "iat",
"accent": "mandarin",
"vad_eos": 5000
}
}
ws.send(json.dumps(data))
thread.start_new_thread(run, ())
websocket.enableTrace(True)
ws = websocket.WebSocketApp(url,
on_message=on_message,
on_error=on_error,
on_close=on_close)
ws.on_open = on_open
ws.run_forever()
```
上面的代码中,我们使用了Python中的websocket库来建立websocket连接,然后将讯飞API所需的参数进行编码,并构造出websocket连接地址。在连接成功后,我们发送开始识别命令,接着可以收到实时的语音识别结果。
