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());
}
