语音识别

  • 语音压缩格式编码
格式名称 格式编码
PCM 1
WAV 2
AMR 3
SILK 4
  • 语音采样率编码
采样率 编码
8KHz 8000
16KHz 16000

语音识别

$res = $ai->aai()->asr([
    'format'   => 2, // 语音压缩格式编码
    'speech'   => base64_encode(file_get_contents('path/to/some_voice.wav')), //待识别语音(时长上限15s)
    'rete'     => 16000 //语音采样率编码
]);


if($res->success()){
    var_dump($res->toArray());
}



长语音识别

speech 与 speech_url任意填写一个即可

$res = $ai->aai()->asrLong([
    'format'        => 1,
    'callback_url'  => 'http://domain.com/callback', //需用户提供后台回调url
    'speech'        => base64_encode(file_get_contents('path/to/some_voice.wav')), //待识别语音(时长上限15nmin)
    'speech_url'    => 'http://domain.com/some_voice.wav' //待识别语音下载地址(时长上限15min)
]);


if($res->success()){
    var_dump($res->toArray());
}

关键词检索

$res = $ai->aai()->detectKeyword([
    'format'        => 1,
    'callback_url'  => 'http://domain.com/callback', //需用户提供后台回调url
    'key_words'      => '天气',  //待识别关键词
    'speech'         => base64_encode(file_get_contents('path/to/some_voice.wav')), //待识别语音(时长上限15nmin)
    'speech_url'  => 'http://domain.com/some_voice.wav' //待识别语音下载地址(时长上限15min)
]);


if($res->success()){
    var_dump($res->toArray());
}
