public class EventLoggerV1 extends AbstractEventLogger
Writes data about a given speech synthesis request for V1 API to the event logs. The data that is logged includes the calling app, length of the utterance, speech rate / pitch, the latency, and overall time taken.

Fields Summary
private final SynthesisRequest
mRequest
Constructors Summary
EventLoggerV1(SynthesisRequest request, int callerUid, int callerPid, String serviceApp)

        super(callerUid, callerPid, serviceApp);
        mRequest = request;
Methods Summary
private java.lang.StringgetLocaleString()
Returns a formatted locale string from the synthesis params of the form lang-country-variant.

            sb.append('-");

            if (!TextUtils.isEmpty(mRequest.getVariant())) {
                sb.append('-");
                sb.append(mRequest.getVariant());
            }
        }

        return sb.toString();
private intgetUtteranceLength()

return
the length of the utterance for the given synthesis, 0 if the utterance was {@code null}.

        return utterance == null ? 0 : utterance.length();

        // total time spent will be inaccurate (will not correlate with
