CMU Dict Grapheme to Phoneme Alignments

November 24, 2019

Grapheme to phoneme alignments for the Carnegie Melon’s pronouncing dictionary data set. Alignments were produced using Phonetisaurus. I couldn’t find an open version of the most recent set of alignments anywhere, so I produced this to save some other people some time.

A grapheme to phoneme alignment maps letters (graphemes) to their sounds when spoken (phonemes). For example the graphemes H,E,LL,O get aligned to the sounds HH,EH0,L,OW1 where the sounds are represented using ARPAbet notation.

Data Engineer Intern @BOLD

June 2019 - August 2019

I interned at the career service company BOLD over the summer of 2019. This job was a really nice extension of some of the embedding projects I was doing earlier in the year for research and it was great to see the technique cropping on in an industry application!

Summary

  • Built backend of semantic search and recommendation system for LiveCareer’s job matching service, incorporated into data pipeline
  • Worked closely with data science team to build set of offline evaluation measures for information retrieval
  • Benchmarked new system against existing one, verified improved relevance and ~80% reduction in preprocessing time
