Why use OpenAI’s Whisper ASR for batch transcription?

Whisper is an open-source deep-learning-based automatic speech recognition (ASR) model developed by Open AI. Whisper is trained on 680,000 hours of multilingual data; which enables it to work well with range of accents and background noise.

Transformer Architecture

The Whisper architecture is a simple end-to-end approach, implemented as an encoder-decoder Transformer.

LLMs for Conversational AI

Developers can easily feed the transcript output to an LLM like GPT for improving transcript readability, summarization, extracting sentiment and more analytics.

Multiple Languages

OpenAI Whisper ASR can transcribe in multiple languages. The following 57 languages have a Word Error Rate of < 50%. Check out our fine-tuning services to get a better ASR.

Fine-tune for better accuracy

Whisper is predominantly trained for English and hence Word Error Rates for other languages might still be high. Voicegain offers Whisper fine-tuning services on your data to get higher accuracy and lower WER.
