Prototype of wheelchair commanded by voice using HMM in a controlled environment
This article presents the development of a recognition system of speaker independent isolated words to command a wheelchair. Each word is encoded using techniques of Linear Prediction and Real Cepstrum, while the classification step is performed using Hidden Markov Models (HMM). From the results, co...

| description | This article presents the development of a recognition system of speaker independent isolated words to command a wheelchair. Each word is encoded using techniques of Linear Prediction and Real Cepstrum, while the classification step is performed using Hidden Markov Models (HMM). From the results, commands are generated to a mobile system (wheelchair), which is led in a controlled environment. |

Este artículo presenta el desarrollo de un sistema de reconocimiento de palabras aisladas independiente del locutor, para comandar una silla de ruedas. Cada palabra se codifica mediante las técnicas de Predicción lineal y Cepstrum real, y la etapa de clasificación se realiza mediante Modelos Ocultos de Markov (HMM). A partir de los resultados se generan órdenes a un sistema móvil (silla de ruedas), el cual es comandado en un ambiente controlado.
