In transcribing the minutes of a meeting from the recording or in a human-machine interface by voice command, ambient voice or noise may make it difficult to hear the desired voice clearly. For this reason, needs for technology that emphasizes only audio in a specific direction is increasing. There is an alternative solution to use a directional microphone, but the cost and size are major issues.

TMC has developed and commercialized a software IP that realizes high-quality sound by beam forming and reducing the ambient noise by noise suppressor for the sound picked up by two inexpensive omnidirectional microphones.

• TM1839

• No patent fees are required taking advantage of using an original voice processing technology.
• Improvements of voice recognition rate and speech intelligibility in recording are possible.
• Excellent cost performance that can process the sound picked up by two inexpensive omnidirectional microphones.
• The simple interface that enables to install in a short period of time.
• Parameterized strength of beamforming and noise suppressor, that enable adjusting according to the devices.
