This paper focuses on the problem of environmental noises in human-human communication and in automatic speech recognition. To deal with this problem, the use of alternative acoustic sensors -which are attached to the talker and receive the uttered speech through skin or bones- is investigated. In the current study, throat microphones and ear bone microphones are integrated with standard microphones using several fusion methods. The results obtained show that the recognition rates in noisy environments are drastically increased when these sensors are integrated with standard microphones. Moreover, the system does not show any recognition degradations in clean environments. In fact, recognition rates also increase slightly in clean environments. Using late fusion to integrate a throat microphone, an ear bone microphone, and a standard microphone, we achieved a 44% relative improvement in recognition rate in a noisy environment and a 24% relative improvement in recognition rate in a clean environment.
