A Brazilian Portuguese Real-Time Voice Recognition to deal with sensitive data

Abstract

Speech recognition is generally performed by a few cloud providers centrally. Such an approach is not suitable for financial and medical institutions because sensitive data cannot be provided openly to third parties. This work proposes a simple chatbot for Brazilian Portuguese real-time speech recognition, well-defined purpose, specific vocabulary, and a secure way without exposing sensitive data for use on mobile devices. The proposed system got a word error rate of 2.38% for a speech recognition task.
