Dr Sam KirkhamLecturer
I am fascinated by speech as a complex biological, physical, cognitive and social system. I have broad interests that span speech acoustics, kinematics, bilingualism, motor control, sociophonetics, sound change, and laboratory phonology. I study these topics across a range of languages and dialects via fieldwork and laboratory research, using methods such as acoustic analysis, ultrasound imaging and electromagnetic articulography. Some of my ongoing research is outlined below.
Bilingual sound systems and phonological representation
My research investigates how bilingual sound systems work, with a focus on language-specific speech production goals, the nature of phonetic and phonological transfer, and speech development. Much of my research in this area has used ultrasound to image the movements of the tongue during speech. I work on languages including English, Punjabi, Twi, Turkish, Sylheti and Scottish Gaelic.

Sociophonetics and laboratory phonology
My PhD focused on sociophonetic variation in high-contact multiethnic communities, during which I also worked extensively on the social meanings of variation. Since then, our group at Lancaster has documented phonetic and phonological variation in the North West of England, which so far includes research on laterals and intonation. More recently, my interests in this area have shifted towards the intersection of sociophonetics and laboratory phonology, with a focus on sound change. Current research focuses on sound change and rhoticity in Blackburn, and regional vowel variation in a large (4000+ speakers) crowdsourced speech corpus.

Speech production and experimental phonetics
I am interested in speech production, including causal models of speech acoustics, articulation and aerodynamics, mechanisms of speech, and speech motor control. I am currently completing a project on adaptation to an artificial palate, as well as conducting new research on the relationship between laryngeal and supralaryngeal kinematics. I am also committed to descriptive research on a diverse range of languages and dialects, which I believe is really important from a sociocultural perspective and also for comprehensively testing our theories.
I teach on the following courses:
- LING102 English Language
- LING223 English Phonetics
- LING327 Advanced English Phonetics
- LING416 Sociophonetics
In 2016 I was awarded Lancaster University's Undergraduate Teaching Award, which is a university-wide prize based on student nominations and testimonials. I have also been nominated for Best Dissertation Supervisor and Best Student Advisor awards at Lancaster, as well as Postgraduate Tutor of the Year when I was a PhD student at Sheffield.
PhD Supervision Interests
I am interested in supervising students who wish to carry out research in the following areas: phonetics, sociophonetics, articulatory phonetics, speech production, phonetics of bilingualism, dialect variation, phonetic fieldwork, South Asian languages and Englishes. I particularly welcome projects that make use of our lab's specialist instrumentation, which includes electromagnetic articulography (EMA), high-speed ultrasound, electropalatography (EPG), electroglottography (EGG), and aerodynamics systems. Please note that I do not supervise topics in applied linguistics, such as pronunciation teaching, and I will only consider studies of second language acquisition that either (i) demonstrate a strong theoretical focus on testing models of bilingualism or L2 speech; or (ii) involve studying the detailed mechanisms of speech production (such as cross-linguistic articulatory strategies).
