However, there are moments when we need to transform spoken words into written form for various purposes. Whether you’re a journalist transcribing an interview, a student transcribing a lecture, or a podcaster creating searchable show notes, converting audio to text can revolutionize how you interact with and share content.

While ASR offers faster results compared to manual transcription, accuracy can fluctuate based on factors like audio quality, accents, and ambient noise. Prominent ASR tools encompass Google’s Speech-to-Text and Microsoft Azure Speech Service.
