133 total talkers of 31 native language backgrounds producing the following in English and, where applicable, in subject's L1: - 120 Hearing in Noise Test (HINT) sentences - 20 sentences pulled from the United Nations Declaration of Human Rights - 30 sentences pulled from Le Petit Prince - The North Wind and the Sun passage - 4 spontaneous storytelling passages - 1 spontaneous speech passage, approximately 5 minutes long
kidLUCID = London UCL Clear Speech in Interaction Database Project title: Speaker-controlled Variability in Children's Speech in Interaction (A research project funded by the ESRC) - 96 talkers (all native southern British English speakers, 46 male, 50 female). Recorded in pairs. - Conversations were constrained by a spot-the-difference puzzle in which pairs of participants verbally compared two scenes, only one of which was visible to each talker (the Diapix elicitation technique). - Each talker participated in total of six Diapix tasks consisting of three conditions. - A total of 288 conversations distributed across three conditions as follows: - NOB (No barrier): 96 conversations while they both heard each other normally. - BAB (Babble): 96 conversations where one conversational partner heard the other's speech in a background for multi-talker babble at an approximate SNR of 0 dB. The talker hearing the babble was a confederate. Exceptions: 4 conversations with CBB ('child multitalker babble' as opposed to 'adult multitalker babble') - VOC (Vocoded): 96 conversations where one conversational partner heard the other's speech after it had been processed in real time through a noise-excited three channel vocoder.
The role of linguistic experience in the processing of probabilistic information during production. 39 speakers from two groups. 17 L1 speakers (13 females) and 22 L2 speakers (17 females). Speakers described a series of events (e.g., The candle rotates). 144 trials included at least 2 events each. TextGrids include RT, determiner, noun, and verb measurements for the third description of (correct) target trials (96 per participant).
Thirty-four native English speakers (21 women) from the Northwestern University community participated. These individuals reported no history of speech or language impairment.
Tongue twisters were composed of syllables with initial consonants contrasting in voicing (e.g., post-boast). Forty-eight pairs of syllables were selected, evenly distributed across labial (/p/, /b/), alveolar (/t/, /d/) and velar (/k/, /g/) place of articulation. For each syllable, four tongue twisters were generated, crossing syllable order (switching, ABBA vs. repeating, ABAB) and which member of the pair was placed first (e.g., within ABBA, post boast boast post vs. boast post post boast).
Each target sequence was presented to participants on a computer screen in a sound-attenuated room. Productions were recorded using a head-mounted microphone. Participants practiced each tongue twister once slowly (1 syllable/second) and then repeated it three times quickly (2.5 syllables/second) in time to a metronome. Only tokens from the fast repetitions of each sequence were analyzed. Trial onset and the onset of fast repetitions was self-paced.
