Python 3.x 语音到文本应用程序：实时计算麦克风中所说的特定单词数

假设您想编写一个python程序，计算麦克风中无限期出现多少个“嘿，Siri”或“嘿，Google”

import sounddevice as sd
import numpy  # Make sure NumPy is loaded before it is used in the callback
import heySiri_recognizer as hsr

heySiri_counter =0
def callback(indata, outdata, frames, time, status):
    if status:
        print(status)
    if indata.hsr():
        heySiri_counter += 1
    outdata[:] = indata
try:
    with sd.Stream(device=(args.input_device, args.output_device),
                   samplerate=args.samplerate, blocksize=args.blocksize,
                   dtype=args.dtype, latency=args.latency,
                   channels=args.channels, callback=callback):
        print('#' * 80)
        print('press Return to quit')
        print('#' * 80)
        input()
        print(heySiri_counter)
except KeyboardInterrupt:
    parser.exit('')
except Exception as e:
    parser.exit(type(e).__name__ + ': ' + str(e))

在上面的代码中，如果您能帮助/评论我如何实现这一点（多线程、异步、块大小（音频缓冲区）等），以及假设的heySiri_识别器模块，我非常感谢
