What is speech recognition?

With Alexa, Siri, Google Assistant & Co., speech recognition has long since arrived in our everyday lives. Whether in a smart home or at work, technology based on artificial intelligence makes our lives much easier.

Speech recognition has developed rapidly in recent years, and recognition rates of up to 99% are now being achieved. It simplifies the conversion of spoken word into text because the time-consuming and costly manual transcription is no longer necessary. Professional users in particular benefit from this, be it in healthcare, journalism, research, public administration or in the media, who always have to offer the content of videos and podcasts as scripts for the purpose of accessibility.

The whole thing is a highly complex process. Explained in simple terms, the analogue speech is first digitized by the automatic speech recognition software and broken down into individual frequencies. Then these sections are compared with already stored phonemes (smallest word units). With the help of the Hidden Markov Model (roughly speaking a kind of modeling model) it is calculated which phoneme is most likely to match. In this way, the individual language snippets are reassembled into whole words and sentences. The application of "deep neural networks", a sub-area of artificial intelligence, makes it possible to quickly recognize and correctly interpret huge amounts of data - important for the accuracy of speech recognition.

Speech recognition is not just speech recognition. Depending on the application, there are different versions.

Assistance systems such as Alexa, Siri or even the professional voice recognition systems are controlled using voice commands. If you say "Siri, read me the new message" or "save the file under Documents", the software executes the command. So you save yourself the manual work.

Speech recognition software for professional dictations offers already stored special vocabularies (for doctors and lawyers). The technical terms contained therein are a good basis for reliable recognition, the software also learns additional words depending on individual use. Punctuation marks, line breaks and new paragraphs must also be dictated, the finished text can be formatted and edited using voice commands. Sensitive patient or client data is automatically password protected. Professional dictation systems with speech processing software are a perfect solution for simplifying the workload and increasing efficiency for industries with high documentation requirements.

Whether meetings, discussion rounds, conferences or interviews - even online meetings can be quickly converted into text form with this software. The speech-to-text software does not need language profiles, but can capture different voices without training and convert their words into writing. No more time-consuming creation of logs, no loss of information, no time-consuming transcription. Conversational speech recognition software, such as GoSpeech, runs on a central server, can be accessed from anywhere and is intuitive to use.
