As much as technology has evolved in the last few years, and even with the advancements in speech recognition software, transcription services still require human review and intervention to assure close to 100% accuracy. Etranscriptions hybrid approach that assures quicker turnaround time and higher accuracy than speech processing software.
Will speech-processing software ever reach human transcriber accuracy? Realistically, this will not happen for a very long time, here are some reasons why:
Accents and speech patterns.
Different regions and people within those regions might have a different way of speaking, which makes training a computer to recognize accents and speech patterns very difficult, even when tested with various sample groups. Moreover, some people slur their words or blend them when speaking very quickly, which can cause additional errors in transcription of the audio. People may stutter or pause to think, which means that the software may include filler words like “um,” “ah,” “hmm,” that should have otherwise been omitted in a clean transcript.
Speech recognition software also requires that you verbalize punctuation versus automatically implementing it (for example, by stating comma, period or colon instead of implying it by the tone of your voice). This makes the transcription of audio from professional speeches, meetings and interviews difficult to transcribe because they will require human review in order to add the appropriate punctuation, and/or to fix any grammar mistakes.
Speech processing software can only recognize words and phrases that it has specifically been trained to recognize. As such, any time that slang or made up terms are used that may not necessarily be in the computer program, the machine will not recognize these terms – this applies to brand names, last names, and other unusual words, such as acronyms or highly technical vocabulary.
Noise, number of speakers, overlapping speech
When multiple speakers are present, they will frequently interrupt each other or speak at the same time, which can be challenging to transcribe for even the most experienced human transcribers. Because computers require clear speech, it is nearly impossible for them to deduce the words accurately and then separate the text by the speaker. A human transcriber may at least be able to figure out who spoke and what they said based on the sound of the speaker’s voice, as well as the previous context.
Additionally, ambient noise from music, talking and even wind noise will affect the accuracy of the transcription, as the computer uses sound bites to figure out the word and these other sounds can cause inaccuracies. Although ambient noise can also be an issue for human transcribers, they can at least try to figure out what is being said.
