Hi there, 

I've created a +12k word British English phonetic dictionary (based on CMUDICT), thought you might be interested:

• +12,000 entries including the top 10,000 most frequent words as per BNC and Google Web Corpus
• IPA transcription including primary and secondary stress
• MIT license
• separate expansion dictionary spelling out punctuation and abbreviations
• both American and British spelling variants

more details on github 

cheers

Jose
