Multisensor speech input was evaluated in operational conditions including an oxygen facemask, different noise conditions, and use with two speech coders and a speech-enhancement system. The authors developed a neckstrap for mounting accelerometers. They selected the best multisensor system and fabricated an exploratory development model (EDM). Results from formal speech intelligibility and quality tests in simulated fighter aircraft noise show that the EDM provides consistently both higher intelligibility and quality, as well as more robust performance under all tested operating conditions, than the microphone alone.
