“…Davis et al (2006) already compared lip articulation under both paradigms and showed that headphones led to significantly more ample articulatory movements. Now, the improved quality of denoising techniques (Mixdorff, Grauwinkel, & Vainio, 2006;Ternström, Södersten, & Bohman, 2002) allows researchers to compare acoustic parameters of speech produced under both paradigms. Several studies have already examined acoustic aspects of Lombard speech, using a loudspeaker paradigm and a dedicated denoising technique (Södersten, Ternström, & Bohman, 2005;Ternstrom, Bohman, & Södersten, 2003, 2006Ternström, Södersten, & Bohman, 2002).…”

These three studies differed from previous studies not only because they used a different immersion method but also because Garnier et al: Sound Immersion and Communicative Interaction 589 other aspects of their protocol were different (e.g., noise types, noise levels, measure of noise levels).…”

“…Noise was then removed from the speech recordings using a dedicated noise-canceling method (Ternström et al, 2002) based on the estimation of the transmission channel and on time-domain subtraction of the estimated noise from the recordings. More details about the principle and performance of this method are presented in Appendix B.…”

“…The audio speech signal was recorded with a cardioid microphone (AKG C1000S) placed 50 cm away from and in front of the speaker's lips and digitized over 16 bits Garnier et al: Sound Immersion and Communicative Interaction 595 at a sampling frequency of 44.1 kHz (Edirol M-100FX). The ambient noise was removed from the speech recordings using the same denoising algorithm (Ternström et al, 2002) as in Experiment 1 and as described in Appendix B. We estimated the impulse response of the transmission channel during a calibration step preceding every noise condition.…”

Purpose: To examine the influence of sound immersion techniques and speech production tasks on speech adaptation in noise. Method: In Experiment 1, we compared the modification of speakers' perception and speech production in noise when noise is played into headphones (with and without additional self-monitoring feedback) or over loudspeakers. We also examined how this sound immersion effect depends on noise type (broadband or cocktail party) and level (from 62 to 86dB SPL). In Experiment 2, we compared the modification of acoustic and lip articulatory parameters in noise when speakers interact or not with a speech partner. Results: Speech modifications in noise were greater when cocktail party noise was played in headphones than over loudspeakers. Such an effect was less noticeable in broadband noise. Adding a self-monitoring feedback into headphones reduced this effect but did not completely compensate for it. Speech modifications in noise were greater in interactive situation and concerned parameters that may not be related to voice intensity. Conclusions:The results support the idea that the Lombard effect is both a communicative adaptation and an automatic regulation of vocal intensity. The influence of auditory and communicative factors has some methodological implications on the choice of appropriate paradigms to study the Lombard effect.

“…[10][11][12][13] In a study of preschool teachers' voices, Södersten et al 14 compared mean fundamental frequency (F0) in a controlled recording to the F0 in the spontaneous speech during work. They found that the mean F0 was higher in the work related recording compared with the controlled condition, indicating that a controlled recording may not reflect mean F0 in spontaneous speech under natural conditions.…”

Summary:A well-controlled recording in a studio is fundamental in most voice rehabilitation. However, this laboratory like recording method has been questioned because voice use in a natural environment may be quite different. In children's natural environment, high background noise levels are common and are an important factor contributing to voice problems. The primary noise source in day-care centers is the children themselves. The aim of the present study was to compare perceptual evaluations of voice quality and acoustic measures from a controlled recording with recordings of spontaneous speech in children's natural environment in a day-care setting. Eleven 5-year-old children were recorded three times during a day at the day care. The controlled speech material consisted of repeated sentences. Matching sentences were selected from the spontaneous speech. All sentences were repeated three times. Recordings were randomized and analyzed acoustically and perceptually. Statistic analyses showed that fundamental frequency was significantly higher in spontaneous speech (P < 0.01) as was hyperfunction (P < 0.001). The only characteristic the controlled sentences shared with spontaneous speech was degree of hoarseness (Spearman's rho = 0.564). When data for boys and girls were analyzed separately, a correlation was found for the parameter breathiness (rho = 0.551) for boys, and for girls the correlation for hoarseness remained (rho = 0.752). Regarding acoustic data, none of the measures correlated across recording conditions for the whole group.
