Based on recordings carried out in an anechoic chamber it is investigated to which degree the voice formants are affected by recording distance and direction in the near field (10, 20, 40, 80, and 100 cm) and different directions (on-axis, horizontally 45 and 90 degrees, vertically +/-45 degrees). This paper present the analysis applied and discusses to what extent the results obtained must be taken into consideration when assessing voice samples for general phonetic research and for automatic voice ID/voice comparisons. It is concluded from the results of the analysis that especially weaker formants are displaced to a not negligible degree.
