<br/>   abstract  = {This paper reports on two experiments that investigated how well listeners
can discriminate between different types of breath noises. We used stimuli
extracted from natural conversations and asked participants to assign them to one of
six breath types (exhalations: oral, nasal; inhalations: oral, nasal, oral followed by
nasal, nasal followed by oral). We further examined if phonetic knowledge, 2 seconds
of speech context around the breath noises, and the breath type of the stimulus
had an influence on the categorization. The results from Experiment 1 suggested
an overall correct assessment rate of 74 %, a tendency for context to help with
categorizing, and similar performance by phoneticians and lay people. Nasal inhalations
were correctly categorized at very high rates, whereas oral exhalations
seemed the most difficult. Experiment 2 further tested these findings and found
an overall rate of 66 %. Nasal inhalations again stood out with very high rates,
whereas nasal exhalations were lowest here. Although we matched the stimuli for
context conditions, we found no significant effect for this factor. While there was
a slight tendency for speech context to be beneficial, we found interactions of this
factor with some breath types, such that for nasal inhalations and nasal followed by
oral inhalations it was more helpful not to have the context.},
