I'm working on an Android Application that record a speech using the mic of the android device, after that i encode the recorded speech into base64 format. to transform the speech into a text i use google speech cloud api and android Volley to send request to google Api. the probleme is when i call the methode for requesting i got this error ==>
E/Volley: [5921] BasicNetwork.performRequest: Unexpected response code 400 for https://speech.googleapis.com/v1/speech:recognize?key={mykey}
Here is My Code :
public class SpeechService {
private String Url ="https://speech.googleapis.com/v1/speech:recognize?key=${mykey}";
private RequestQueue requestQueue ;
private AppCompatActivity app ;
String savedata ;
public SpeechService(AppCompatActivity app){
this.app = app ;
requestQueue = Volley.newRequestQueue(app.getApplicationContext());
}
public void getTextFromGSpeech1(String EncodedSpeech){
JSONObject jsonObject = new JSONObject();
JSONObject config = new JSONObject() ;
JSONObject audio = new JSONObject() ;
try {
config.put("encoding", MediaRecorder.OutputFormat.AMR_WB);
config.put("SampleRateHertz","rba9 rba9");
config.put("languageCode","fr-FR");
audio.put("content",EncodedSpeech);
jsonObject.put("audio", audio );
jsonObject.put("config", config);
} catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest JObjectREQUEST = new JsonObjectRequest(Request.Method.POST , Url , jsonObject ,new Response.Listener<JSONObject>(){
@Override
public void onResponse(JSONObject response) {
System.out.println("JSON response is ============> ");
System.out.println(response);
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
System.out.println("failed ...............;");
}
}){
@Override
public String getBodyContentType() {
return "application/json; charset=utf-8";
}
};
requestQueue.add(JObjectREQUEST);
}
}
and the Json object format must be like this
{ "audio": {
"content": ""
}
,
"config": {
"encoding": "ENCODING_UNSPECIFIED",
"languageCode": "fr-FR",
"sampleRateHertz": 1600
}
}
