Vietnamese Streaming RNN-T

• This model runs on a very slow CPU (it's Free tier) so the RTF of FP32 model is around 1.5 (which means it will take 1.5 times the duration of the audio to process it).
• This model mights not work with your microphone since it was trained on a quite clean dataset. Try to speak loudly 😃
• Although you upload a full audio file, the model will process it in a streaming fashion.
