A hands-free speech communication device for an emergency call system, the hands-free speech communication device comprising: a housing disposed in a vehicle cabin; a speaker which is housed in the housing and outputs from a first surface of the housing a reception sound of a communication party; a microphone which is housed in the housing and collects sound from the first surface of the housing, the microphones including: a first omnidirectional microphone and a second omnidirectional microphone disposed at positions which are axisymmetric with a line segment as a symmetric axis, the line segment extending in a radial direction from a center of a diaphragm of the speaker; and a third omnidirectional microphone disposed at a position which is on the symmetric axis and is closer to the speaker than the first omnidirectional microphone and the second omnidirectional microphone are; and a sound processor including: a beam former which is connected to the first omnidirectional microphone and the second omnidirectional microphone and forms a bidirectionality in which directionality is strong in two directions each perpendicular to the symmetric axis and is weak in two directions each along the symmetric axis; and an echo cancel unit which is connected to the beam former and the third omnidirectional microphone and removes a sound signal having been output from the third omnidirectional microphone from a sound signal having been output from the beam former. a housing disposed in a vehicle cabin; a speaker which is housed in the housing and outputs from a first surface of the housing a reception sound of a communication party; a microphone which is housed in the housing and collects sound from the first surface of the housing, the microphones including: a first omnidirectional microphone and a second omnidirectional microphone disposed at positions which are axisymmetric with a line segment as a symmetric axis, the line segment extending in a radial direction from a center of a diaphragm of the speaker; and a third omnidirectional microphone disposed at a position which is on the symmetric axis and is closer to the speaker than the first omnidirectional microphone and the second omnidirectional microphone are; and a first omnidirectional microphone and a second omnidirectional microphone disposed at positions which are axisymmetric with a line segment as a symmetric axis, the line segment extending in a radial direction from a center of a diaphragm of the speaker; and a third omnidirectional microphone disposed at a position which is on the symmetric axis and is closer to the speaker than the first omnidirectional microphone and the second omnidirectional microphone are; and a sound processor including: a beam former which is connected to the first omnidirectional microphone and the second omnidirectional microphone and forms a bidirectionality in which directionality is strong in two directions each perpendicular to the symmetric axis and is weak in two directions each along the symmetric axis; and an echo cancel unit which is connected to the beam former and the third omnidirectional microphone and removes a sound signal having been output from the third omnidirectional microphone from a sound signal having been output from the beam former. a beam former which is connected to the first omnidirectional microphone and the second omnidirectional microphone and forms a bidirectionality in which directionality is strong in two directions each perpendicular to the symmetric axis and is weak in two directions each along the symmetric axis; and an echo cancel unit which is connected to the beam former and the third omnidirectional microphone and removes a sound signal having been output from the third omnidirectional microphone from a sound signal having been output from the beam former.
