Speech recognition terms: a voice input glossary

Mark Vesyoly · founder of Potok · ~9 min

Potok turns speech into text in 33 languages, including English and Russian.

Speech recognition terms describe different parts of one technology: voice input is the general name, speech recognition (ASR) is the process of turning sound into text itself, and dictation is the same thing from the user's point of view. Potok (potok.now) has a response time of about 0.4 seconds: hold the hotkey, speak, release, and the text is ready.

Speech recognition, ASR, dictation, hotkey, WER: behind these words there are often simple things that are easier to explain in one phrase than to work out from context. Voice input as a phenomenon and the specific technical terms inside it are things of different levels, and they are easy to mix up.

Which terms to start with

Where Potok does not fit

These terms describe the technology as a whole, and not what Potok specifically can do. For example, offline recognition from the list above exists in some programs, but not in Potok: it is a cloud service, recognition runs on servers in Russia, and it does not work without the internet. Transcription of finished audio files and recordings is not what Potok does either: it recognizes live speech at the moment of dictation and does not transcribe what is already recorded. For finished recordings Potok has a Telegram bot, @potok_now_bot.

Frequently asked questions

How is speech recognition different from voice input

Speech recognition (ASR) is the technology of turning sound into text itself, while voice input is how this technology is applied in practice: a hotkey, recording, inserting text into a field. ASR is part of voice input, not the same thing: voice input also includes the interface, the hotkey and inserting text into the active window.

What is WER and why is this number important

WER (word error rate) is the share of words recognized with an error out of the total number of words in the text. The smaller the number, the more accurate the program: a WER of 5% means that on average about every twentieth word is wrong. It is the standard metric for evaluating the quality of speech recognition systems.
