Some apps claim to have ‘noise-cancellation’ features, but that generally fails when the background noise is loud. How’s the Audio Quality?Īudio-to-text converters require clearly audio to transcribe accurately. If you mostly dictate or record single-speaker audio, then an audio-to-text converter is a good choice.īut if most of your audio is multi-speaker (interviews, focus groups, meetings, etc.), then you may want to consider manual transcription or outsourcing. Of course they would still produce some form of a transcript, but you may find that making corrections takes the same amount of time as transcribing the whole thing manually (sometimes longer). Therefore the accuracy of audio-to-text converters is quite low on multi-speaker audio. How many speakers are there on your recording?Īs we know, speech recognition technology is primarily geared towards single-speaker audio. If you are into research, then this shouldn’t be a problem because you would re-listen to the recording anyway.īut if you’re a journalist or podcaster then the proofreading will mean additional time and effort and may affect deadlines.

If you need pre-recorded audio or video transcribed, then these are more appropriate for you. Transcription apps allow you to upload a recording and create a transcript from it. then dictation apps would be a good choice. If you’re looking for an app to take notes, write a book, dictate patient reports, etc. The downside is that the accuracy of transcripts produced by these applications is inconsistent (ranging between 40-95%).Īs the name suggests, dictation apps transcribe your speech real-time as you talk into a microphone. The upside of using audio-to-text converters is that they can obviously save you a ton of time and energy by automating what is otherwise a very tedious and manual process. ![]() Today, practically every dictation and transcription app worth talking about uses speaker dependent speech recognition technology in combination with AI/Machine Learning.
