Hello , i don’t understand why use model.intermediateDecode it will print all word listened,how to make it just print one word listening. i using sample android_mic_streaming.Here code to use model in it:
streamContext = model.createStream(), 0, audioBufferSize) model.feedAudioContent(streamContext, audioData, audioData.size) var decoded = model.intermediateDecode(streamContext) runOnUiThread { transcription.text = decoded }
