Speech Perception


The speech perception research in the lab centers on questions of language sound change and synchronic phonological structure. Speech Perception research is supported by a two-room suite, where participants are tested in small sound isolated booths. In addition, we have an eye tracking lab for the psycholinguistic study on-line word and sentence processing.

In recent years, research on speech perception in the PhonLab has centered on cognitive mechanisms that are involved in using context in processing speech - in talker ‘normalization’ (Sjerps & Johnson, 2018; Johnson, 2018), in language effects in code-switching (Shen, 2017); sound symbolism (Shibata, 2018); semantic predictability (Manker, 2016); intonation perception (Dil, 2018), and in sound change in progress (Johnson & Song, 2016).

Articulatory Phonetics

In Sasha Calhoun, Paola Escudero, Marija Tabain & Paul Warren (eds.) Proceedings of the 19th International Congress of Phonetic Sciences, Melbourne, Australia.

Speech production studies in the lab focus on the human system of articulatory control in English and other languages, and in ordinary speech as well as in response to experimental manipulations. Facilities for speech production research are housed in a 500 square foot research lab with a large double-walled sound-attenuated recording booth. The lab also houses equipment for articulatory research using ultrasound, Electromagnetic Articulography (EMA), aerodynamics, static palatography, electro-palatography (EPG), and electro-glottography (EGG). Access to corpora of acoustic speech production and speech articulation such as the X-Ray Microbeam Database also facilitate PhonLab research in this area.

Recent research includes work on gestural magnitude and timing, extra-linguistic variation (e.g. individual anatomical variation), and the effects of articulatory training. Work on gestural timing focuses on the production of gestural timing in complex segments, investigating the coordination of multiple articulations within and between segments. Research investigating the interaction between linguistic and extra-linguistic variation may lead us to a better understanding of sound change. Other projects include work on articulatory training, asking people to alter their articulations, in various experimental paradigms to study the limits of speech motor control in adults, and the cross-linguistic tuning of speech motor control regimes.

Phonology



In recent years, there has been considerable work at Berkeley on the analysis, history, and typology of segmental, subsegmental, and prosodic phonology, with special attention to their interfaces with phonetics, morphology, and syntax. This has led to the development of specific theories (subsegmental Q-theory, Optional Construction Morphology) and numerous single and joint publications between faculty, students, and visitors.

Phonological Learning and Language Acquisition


Glewwe, Eleanor, Jesse Zymet, Jacob Adams, Rachel Jacobson, Anthony Yates, Ann Zeng, and Robert Daland. 2018. Substantive bias and final (de)voicing: an artificial grammar learning study. Annual Meeting of the Linguistic Society of America, Salt Lake City, Utah.

Another significant area of research in the PhonLab concerns the study of phonological learning. Ongoing work in this area includes both the study of child speech acquisition as well as the development and comparison of theoretical and computational models of phonology and its interfaces with other grammatical components such as morphosyntax and phonetics, and language acquisition. Research on childhood development has focused on the development of speech coupled with the anatomical developments in childhood language learning as well as the acquisition of phonological structure such as complex segments, e.g. lateral /Cl/ clusters.

Research on models of phonology and phonological acquisition employs experimental methods, including nonce probe studies and artificial grammar learning experiments, to validate theoretical proposals and to deepen our understanding of language learning by children and the biases they carry. Recent research has focused on phonetic naturalness bias in phonological learning, as well as the acquisition of morpheme-specific phonology in Slovene and French.

Causes and Consequences of Pronunciation Variation



Research in the lab dealing with pronunciation variation includes work on the acoustics of code-switching (Shen, Gahl, Johnson, 2018) and on the effects of phonological neighborhood density on lexical access and pronunciation.

Sociophonetics



The sociolingusitics of phonetic identity (particularly in regional dialect and gender and sexual identity) and of phonetic accommodation is a focus interest and energy in the PhonLab. Research in sociophonetics is made possible by an audio video recording studio, and by the conversational language recording space SPARCL. As well as great web application programming support from Ronald Sprouse.

The SPARCL (Sociophonetic Area for Recording Conversational Language) is a resource for conducting research in the areas of sociolinguistics, sociophonetics, discourse analysis, and gesture analysis. It is designed for eliciting naturalistic speech data in a comfortable environment. The lab is equipped with video cameras and high quality audio equipment, in a living room style décor. Financial support for SPARCL was provided by the Department of Linguistics, the Department of Spanish and Portuguese (thanks Justin Davidson), and by a UC Berkeley "Student Technology Fund" award won by lab graduate students.

Recent research includes the "Voices of Berkeley" project which collected phonetic data from over 700 students at Berkeley using students' own computer and a web-interface. We have recently begun to publish results of this project and make plans for a larger, more representative sample.
