+ * A service that allows interaction with the actual sound trigger detection on the system.
+ *
+ * <p> Sound trigger detection refers to detectors that match generic sound patterns that are

+ * android.service.voice.VoiceInteractionService} instead. Access to this class needs to be
+ * protected by the {@value android.Manifest.permission.BIND_SOUND_TRIGGER_DETECTION_SERVICE}
+ * permission granted only to the system.
+ *
+ * <p>This service has to be explicitly started by an app, the system does not scan for and start
+ * these services.
+ *
+ * <p>If an operation ({@link #onGenericRecognitionEvent}, {@link #onError},
+ * {@link #onRecognitionPaused}, {@link #onRecognitionResumed}) is triggered the service is
+ * considered as running in the foreground. Once the operation is processed the service should call
+ * {@link #operationFinished(UUID, int)}. If this does not happen in
+ * {@link SoundTriggerManager#getDetectionServiceOperationsTimeout()} milliseconds
+ * {@link #onStopOperation(UUID, Bundle, int)} is called and the service is unbound.
+ *
+ * <p>The total amount of operations per day might be limited.
