Abstract

Voice problems are common among workers in occupations with high demands on oral communication. For sustaining vocal health, it is important to find efficient ways for how to reduce strain on the voice at work, and one way to do so is optimizing the room acoustics for communication. However, to date we do not know enough about what kind of room acoustic conditions that support voice and speech most efficiently. The purpose of this project is to investigate how different acoustic environments affect voice and speech in talkers. To do so, an experimental set-up has been developed for acoustic as well as visual simulation of different room conditions, using real-time auralization of a speaker's own voice in a 64-loudspeaker array in an...

Voice problems are common among workers in occupations with high demands on oral communication. For sustaining vocal health, it is important to find efficient ways for how to reduce strain on the voice at work, and one way to do so is optimizing the room acoustics for communication. However, to date we do not know enough about what kind of room acoustic conditions that support voice and speech most efficiently. The purpose of this project is to investigate how different acoustic environments affect voice and speech in talkers. To do so, an experimental set-up has been developed for acoustic as well as visual simulation of different room conditions, using real-time auralization of a speaker's own voice in a 64-loudspeaker array in an anechoic room combined with virtual reality. Room conditions vary in room size, reverberation time and the speaker-oriented room acoustic parameters voice support and room gain. These parameters quantify the own-voice amplification provided by room reflections to the talker's own ears. In this paper, the experimental set-up and study protocol development will be presented and discussed.
