幽冥大陆(五十七)ASR whisper-cli命令行使用 C语言—东方仙盟筑基期

whisper-cli 实际通常指 whisper.cpp 提供的命令行工具(main 可执行文件),以下是 Windows 环境下的核心使用说明,适配轻量级、CPU 优先的本地化语音识别需求:

一、 基础命令格式

bash

运行

复制代码
./main -m models/ggml-base.en.bin -f audio.wav

核心参数说明:

  • -m <model-path>:指定模型文件路径(必须项,需提前下载对应量化模型,如 ggml-base.en.bin
  • -f <audio-path>:指定待识别的音频文件路径(支持 WAV/MP3 等,推荐 16kHz 单声道 WAV)

二、 关键优化参数(适配 CPU 优先 + 实时需求)

  1. 量化与低资源配置

    bash

    运行

    复制代码
    ./main -m models/ggml-tiny.en.bin -f audio.wav -c 0 --threads 4
    • -c <ctx-size>:设置上下文窗口大小,-c 0 自动适配,降低内存占用
    • --threads <num>:指定 CPU 线程数(建议设为 CPU 核心数的一半,平衡速度与资源消耗)
    • 模型选择:优先选 tiny/base 级别的英文模型(ggml-tiny.en.bin),体积小、识别快,适合垂直领域指令
  2. 实时语音识别(麦克风输入)

    bash

    运行

    复制代码
    ./main -m models/ggml-base.en.bin --mic 1 --step 500 --length 5000
    • --mic <device-id>:指定麦克风设备 ID(Windows 下可通过 ./main --list-mics 查看设备列表)
    • --step <ms>:实时识别的步长(单位毫秒,越小越实时,建议 500)
    • --length <ms>:每次识别的音频长度(建议 5000,即 5 秒)
  3. 垂直领域优化(商业服务指令)

    bash

    运行

    复制代码
    ./main -m models/ggml-base.en.bin -f audio.wav -k 10 --prompt "收款 配镜 验光 取镜"
    • --prompt <text>:添加领域关键词提示,引导模型优先识别商业服务相关指令
    • -k <max-words>:限制输出最大词数,适配短语音指令场景

三、 输出与格式控制

  • -otxt:将识别结果保存为 TXT 文件

  • -ojson:输出 JSON 格式结果(便于程序调用)

    bash

    运行

    复制代码
    ./main -m models/ggml-base.en.bin -f audio.wav -ojson
