Abstract Recently, with rapid progress in multimedia technologies, hopes for a speech‐based man‐machine interface have increased. For high‐quality voice collection and acquisition of the position information of the speaker, direction‐of‐arrival (DOA) estimation technology for voice with a microphone array has been discussed. However, one problem is large‐scale implementation of the arrays. In the present research, a new DOA estimation method for a two‐channel microphone array based on the harmonic structure of vowels is proposed. The present method has been applied in a real‐world environment and its effectiveness has been confirmed. © 2002 Wiley Periodicals, Inc.
