The effect of interpersonal familiarity on auditory distance perception of reverberant speech

Description of this data

Familiarity with sound sources is known to have a modulatory effect on auditory distance perception. However, the level of familiarity that can affect distance perception is not clearly understood. A subjective experiment that aims to assess the effect of interpersonal familiarity on auditory distance perception is reported in this article. The experiment involves a binaural listening task where different source distances between 0.5 and 16 meters were emulated by convolving dry speech signals with binaural room impulse responses measured in a skyway. The experimental paradigm involved stimuli that consisted of speech signals recorded from different-gender couples who have self-reported to have known each other for at least a year with daily interaction. Each subject judged the distances of a total of 15 different speech stimuli from their partner, the spectrally most similar stranger and the spectrally most dissimilar stranger, for six different emulated distances, respectively. The main finding is that a similar but unfamiliar speaker is localized to be further away than either a familiar speaker or an unfamiliar speaker.

Steps to reproduce

Part1-Recording the Speech sounds

  1. Record the distance parameters from the hall (BRIRs) via DummyHead mic
  2. Use gammatone filterbank code to analyze the participants' raw speech files to group them into 3 familiarity levels for every participant based on the spectral comparison of their partner's recorded voice. (V0: Partner's voice, V1: spectrally similiar voice of a stranger participant, V2: spectrally dissimilar voice of a stranger participant)
  3. Convolve all the speech files with the measured BRIRs for the selected distances (in this case; .5, 1, 2, 4, 8, 16m)
  4. Create sound file documents for each participant (Containing 90 speech files each)---6distance X 3familiarty X 5sentence
    Part2: Each participant listens to 90 different sound stimulus and makes judgements of the distances for each sound file
  5. Data analysis for the distance judgements
