Hands-free speech communication device for an emergency call system

There is provided a hands-free speech communication device for an emergency call system of a speaker and microphone integrated type in which the speaker and the microphone are housed in the same housing, and at the same time, influence of the speaker to the microphone is reduced. A speech communication device 20 is equipped with a microphones M configured with: microphones M1 and M2 disposed at positions which are axisymmetric with a centerline CL in a width direction of a housing 30 as a symmetric axis; and a microphone M3 disposed at a position which is on the centerline CL and closer to a speaker SP than the microphones M1 and M2 are. The speech communication device 20 is further equipped with: a sound processor 100 which includes: a beam former 102 which is connected to the microphones M1 and M2 and forms a bidirectionality 102c in which directionality is strong in two directions each perpendicular to the centerline CL and is weak in two directions each along the centerline CL; and an echo cancel unit 103
