猖写脚本 test-speed.py

import argparse
import whisper

# 创建䞀䞪解析噚
parser = argparse.ArgumentParser(description='Transcribe a speech file using a specific model.')
parser.add_argument('speech_file', type=str, help='The path to the speech file.')
parser.add_argument('model', type=str, help='The model to use for transcription.')

# 解析呜什行参数
args = parser.parse_args()

# 䜿甚指定的音频文件和暡型进行蜬圕
text = whisper.transcribe(args.speech_file, model=args.model, initial_prompt='倧家奜')["text"]
print(text)

执行脚本

time python test-speed.py test.wav base

䞋面的性胜测试䜿甚的是䞀䞪 5 分钟的音频文件 test.wav。
