Weberated transcripts) data to boost the performance of the ASR trained in an supervised manner. There have been many recent studies leveraging untranscribed data during ASR training; for example, pre-training and self-training methods in end-to-end ASR systems [24]. Other research has leveraged non-annotated data for ASR in low-resource languages ... WebNov 23, 2024 · Automatic speech recognition (ASR) is a technology which converts voice into text transcriptions and is one of the core techniques in man-to-machine communications. In recent years, several applications have extensively used ASR-related speech technologies for information access and speech-to-speech translation services.
