Whisper, by OpenAI, is a powerful model for automatic speech recognition (ASR) and speech translation. It was trained on an extensive dataset of over 5 million hours of audio, including 1 million hours with human-provided labels and 4 million hours with machine-generated labels. This large-scale, diverse training allows Whisper to accurately transcribe and translate speech in various languages and accents without additional adjustments, making it highly adaptable to new datasets and audio contexts. Its zero-shot capabilities enable it to perform well in previously unseen situations, making it ideal for transcription, live translation, and other real-world applications.
