Question

我已经尽我所知来获取Google Speech to text API的返回值，但返回false却无济于事。我确保我的flac文件是一个单通道文件（ffmpeg -i test.flac -ac 1 test1.flac）-仍然没有。我在做什么错了？

<?php
// Your API Key goes here.
$apiKey = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX';
$audioFile = realpath(__DIR__ . '/test.flac');
$url="https://speech.googleapis.com/v1/speech:recognize?key={$apiKey}";
$audioFileResource = fopen($audioFile, 'r');
$base64Audio = base64_encode(stream_get_contents($audioFileResource));
$settings=array(
    'config'=> array(
        'encoding'=>'FLAC',
        'sampleRateHertz'=>44100,
        'maxAlternatives'   => 3,
        'languageCode'      => 'en-US'
    ),
    'audio'=>array(
        'content'=>$base64Audio
    )
);
$json=json_encode($settings);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,            $url );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($ch, CURLOPT_POST,           1 );
curl_setopt($ch, CURLOPT_POSTFIELDS,     $json ); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER,     array('Content-Type: application/json')); 

$result=curl_exec ($ch);
var_dump($result);
exit;

更新：我已经更新了代码，现在可以使用了。我错了两件事。首先是配置设置中的“ sampleRateHertz”而不是“ sampleRate”。其次，我必须在对等端禁用SSL验证。现在可以使用了。

返回以下内容：

    D:\>php GoogleSpeechToText_example.php
string(320) "{
  "results": [
    {
      "alternatives": [
        {
          "transcript": "the quick brown fox jumped over the lazy dog",
          "confidence": 0.9850106
        },
        {
          "transcript": "the quick brown fox jumps over the lazy dog",
          "confidence": 0.90610087
        }
      ]
    }
  ]
}

Answer 1

幸运的是，我发现了问题所在。我必须添加以下代码行：

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

Google Speech to Text API仅返回false
