Language production of sequences
Relevant publications:  
Compound words and multiword expressions are complicated — we have to identify, remember, and then produce them fluently. When speakers are producing compounds, are they planned and produced like monomorphemic words? And when we retrieve phrases for production, is the process similar, or more discrete? My work has shown that compounds are produced similarly to monomorphemic words (Jacobs & Dell, 2014), but that phrases are decomposable, and retrieving one word from a phrase triggers the retrieval of the other to the extent that they co-occur (Jacobs, Dell, & Bannard, 2017).
Episodic memory for multiword sequences
Relevant publications:  
A number of theories have proposed that multiword sequences are stored as unanalyzed wholes in long-term memory. As part of my dissertation work, I used novel applications of recognition memory and free recall experiments to understand phrase processing (i.e. Jacobs, Dell, Benjamin, & Bannard, 2016; Jacobs, Dell, & Bannard, 2017). I have found that phrase frequency effects can still arise in the presence of incremental production, without needing to posit phrase representations per se. More recently, I have been investigating whether phrase frequency effects arise spontaneously during the recall of visual information (Jacobs & Ferreira, in prep).
The role of auditory memories in speakers’ prosodic decisions
Relevant publications: 
Research on spoken word production tends to focus on the mechanics and/or goals that affect the phonetic forms of speakers’ utterances. Context and experience, however, influence speakers’ decisions. But what experience matters? Can simply saying a word in your head change your fluency? In a series of several projects, I have found that hearing a word is critical for production decisions (Jacobs et al., 2015; Buxó-Lugo, Jacobs, & Watson, submitted), though it is not the only factor, as speakers reduce even when auditory input is degraded (Jacobs, Loucks, Watson, & Dell, in prep).
Natural language processing for cognitive models of learning and memory
A substantial body of literature exists to explain episodic memory and semantic memory for words. More recently, I have been integrating cutting edge techniques for learning the meanings of words and phrases from text to explain memory for words and phrases as an implementation of the verbal model in my dissertation. These models specifically draw on context-based accounts of linguistic representations and of memory, in which context evolves over time and is used to anchor meaning.
Phoneme-level models of sequence production
Many computational models of prosodic production or speech rate are trained on idealized input unrelated to linguistic categories. What can we learn about phonemes from distributional data? Can we predict phoneme-by-phoneme when speakers will encounter difficulty or experience facilitation? How much do simple models line up with empirical evidence?
Building distributional semantic models of words, phrases, and entities
Building word, phrase, and entity embeddings can be difficult and require significant hacking of existing packages. When working with traditional matrix factorization methods, the input space can be transformed to your liking. The nontology package makes that easy.
Easier forced alignment and annotation in Praat [Coming soon!]
Running the p2fa forced aligner lost me a lot of time. I’ve since discovered gentle, which I combine with praatio to make forced aligning easy in Praat. No more stress over a forced aligner pipeline that breaks! Keep your eyes peeled for updates to gently!
