DeepSpeech is an open-source speech recognition engine developed by Mozilla. It uses deep learning techniques to convert spoken language into text, making it easier for applications to understand human speech. The model is trained on a large dataset of audio recordings and their corresponding transcripts, allowing it to recognize various accents and languages. The architecture of DeepSpeech is based on a neural network that processes audio input and outputs text. It is designed to be efficient and can run on different platforms, including desktops and mobile devices. This technology aims to improve accessibility and enhance user experiences in voice-driven applications.
