The Human Speechome Project is an effort to observe and computationally model the longitudinal course of language development for a single child at an unprecedented scale. The idea is this: Instrument a child's home so that nearly everything the child hears and sees from birth to three is recorded. Develop a computational model of language learning that(More)
PURPOSE The Lombard effect describes the tendency for speakers to increase pitch, intensity, and duration in the presence of noise. It is unclear whether these modifications are uniformly applied across all words within an utterance or whether information-bearing content words are further enhanced compared with function words. In the present study, the(More)
Current speech synthesis technology is difficult to understand in everyday noise situations. Although there is a significant body of work on how humans modify their speech in noise, the results have yet to be implemented in a synthesizer. Algorithms capable of processing and incorporating these modifications may lead to improved speech intelligibility of(More)
UNLABELLED Splenosis is a rare finding of ectopic splenic tissue found within the thoracic cavity, abdomen or peritoneal cavity. Most cases occur in the abdomen and the thoracic location is a comparatively rare finding. In thoracic splenosis the splenic tissue most often grows in the form of a nodule and the autotransplantation is usually caused by a(More)
Does consuming more goods make people happier? For a broad spectrum of goods, available evidence suggests that beyond some point the answer is essentially no. Much of this evidence is from the large and growing scientific literature on the determinants of life-satisfaction and psychological well-being. 1 Evidence from this literature also suggests, however,(More)
Speakers with severe dysarthria are known to have reduced range in prosody. Consistent control within that range, however, has largely been ignored. In earlier investigations speakers with severe dysarthria were able to control pitch and duration for sustained vowel production despite reduced flexibility of control (Patel, 1998). The present experiment(More)
The population with severe speech and motor impairments (SSMI) depend solely on the Augmentative and Alternative Communication Techniques (AAC) for their education and communication needs. Unfortunately, the AAC tools are expensive with respect to the Indian people and the language being English is not usable by the majority of the population. Also, the AAC(More)
This study explored the relationship between articulator movement and prosody in children at different developmental ages. Jaw, lower lip, and upper lip kinematics were examined in 4-, 7-, and 11-year-old children as they produced the declarative and interrogative forms of utterances "Show Bob a bot" and "Show Pop a pot." Articulator movement differences(More)
Prosodic features of the speech signal include fundamental frequency (F0), intensity and duration. In order to study the development of prosody independent from segmental aspects of speech, we considered the question–statement contrast. In English, adults mark the contrast using changes in fundamental frequency, duration and intensity, with F0 being the(More)
Parallel isolated word corpora were collected from healthy speakers and individuals with speech impairment due to stroke or cerebral palsy. Surface electromyographic (sEMG) signals were collected for both vocalized and mouthed speech production modes. Pioneering work on disordered speech recognition using the acoustic signal, the sEMG signals, and their(More)
