  • Hands-free speech communication device for an emergency call system
    Patent number: 9913084
    Abstract: A speech communication device includes microphones configured with: microphones M1 and M2 disposed at positions which are axisymmetric with a centerline in a width direction of a housing as a symmetric axis; and a microphone M3 disposed at a position which is on the centerline and closer to a speaker than the microphones M1 and M2 are. The speech communication device is further equipped with: a sound processor which includes: a beam former which is connected to the microphones M1 and M2 and forms a bidirectionality in which directionality is strong in two directions each perpendicular to the centerline and is weak in two directions each along the centerline; and an echo cancel unit which is connected to the beam former and the microphone M3 and removes a sound signal having been output from the microphone M3 from a sound signal having been output from the beam former.
