Acoustical analyses were carried out on the digits 0-9 spoken by two male speakers in quiet and in 90 dB SPL of masking noise in their headphones. The results replicated previous studies demonstrating reliable increases in amplitude, duration, and vocal pitch while talking in noise. Reliable differences were also found in the tilt of the short-term spectrum of consonants and vowels. The results are discussed in terms of: (1) the development of algorithms for recognition of speech in noise; (2) the nature of the acoustic changes that take place when speakers produce speech under adverse conditions such as noise, stress, or high cognitive load; and (3) the role of training and feedback in controlling and modifying a person's speech to improve performance of current speech recognizers.
