How does Notta work?
Speech recognition is a technology that has been improved over half a century to convert spoken words into text. It is used for various applications like voice assistants, transcriptions, and voice biometrics. Technologies such as deep learning and big data are used for speech recognition. The initial steps of speech to text involve converting speech to digital format, audio classification, and spectrogram analysis. The speech-to-text software utilizes linguistic algorithms to categorize auditory signals of speech and convert them into Unicode. The process involves analog to digital conversion, filtering, segmentation, character integration, and the final transcript. Custom speech-to-text solutions can increase transcription accuracy, which makes it useful across industries.
1- Analog To Digital Conversion: When human beings utter words and make sounds, it creates different sequences of vibrations. A speech-to-text model would specifically pick up these vibrations which are technically analog signals. An analog to digital converter then takes these vibrations as input to convert to a digital language.
2- Filtering: The sounds picked up and digitized by the analog to digital converter are in a form that is machine-consumable as an audio file. The converter analyses the audio file comprehensively and measures the waves in great detail. An underlying algorithm then classifies the relevant sounds and filters them to pick up those sounds that can eventually be transcribed.
3- Segmentation: Segmentation is done on the basis of phonemes, which are linguistic devices that differentiate one word from another. This unit of sound is then compared against segmented words in the input audio for matching and predicting the possible transcriptions. There are approximately 40 phonemes in the English language and similarly, there are thousands of other phonemes across all the languages.
4- Character Integration: The speech-to-text software consists of a mathematical model consisting of various permutations and combinations of words, phrases, and sentences. The phonemes pass through a network consisting of elements of the mathematical model so that the most commonly occurring elements are compared to these phonemes. The likelihood of the probable textual output is calculated at this stage for integrating the segments into coherent phrases or segments.
5- Final Transcript: The audio's most likely transcript is presented as text at the end of this process based on deep learning predictive modeling. A computer-based demand generated from the above probabilities is then produced from the built-in dictation capabilities of the device that is being used for transcription.
