我尝试使用JSON和下面的代码片段向https://speech.googleapis.com/v1/speech:recognize发送POST请求 . 不知何故谷歌回应说我的请求无法解码Base 64 .
{“config”:{“encoding”:“LINEAR16”,“sampleRateHertz”:16000,“languageCode”:“ja-JP”,“maxAlternatives”:5,“profanityFilter”:false},“audio”:{“content” “:”ZXCVBNM“},}
String pcmFilePath = "/storage/emulated/0/Download/voice8K16bitmono.pcm";
File rawFile = new File(pcmFilePath);
byte[] rawData = new byte[(int) rawFile.length()];
DataInputStream input = null;
try {
input = new DataInputStream(new FileInputStream(rawFile));
int readResult = input.read(rawData);
} catch (Exception ex) {
ex.printStackTrace();
}
if (input != null) {
input.close();
};
String base64 = Base64.encodeToString(rawData, Base64.DEFAULT);
String completePostBody = postBody.replace("ZXCVBNM" , base64);
“code”:400,“message”:“'audio.content'(TYPE_BYTES)的值无效,Base64解码失败为\”...
有没有人有任何建议?

我设法从Google Speech API获得了结果 .
据记载,Base 64编码不应该有换行链接:https://cloud.google.com/speech/docs/base64-encoding
从
Base64.DEFAULT
改为Base64.NO_WRAP
在我的案例中起作用 . pcm文件也应该是LSB
