ConvertIPA phonetic notation to speech

how does it work?

Using the computational capabilities exposed by your browser's JavaScript processor, theIPA phonetic notation is translated into phonemes understood byeSpeak using correspondences and logic found inlexconvert. The translated phonemes (e.g., [[mUm'baI]] for /mʊmˈbaɪ/) are then provided tomeSpeak.js, a revisedEmscripten'd version of eSpeak for output. Once the output has been generated, the pronunciation inWAV format is downloadable.

As this processing takes place within your browser, this page may be downloaded and used offline. By extension, the requested pronunciations are not logged.

Enrich theIPA-phoneme correspondence list. For English, eSpeak recognizes 96 phonemes (dictsource/dict_phonemes). Currently, only 55 are mapped using lexconvert and there may have been mistakes in interpreting lexconvert's conversion scheme. Additional correspondences should improve pronunciation.

Contribute to the underlying libraries. eSpeak, meSpeak.js, or the most current Emscripten'd variation to improve performance/size. meSpeak.js is currently over two megabytes.

about

This browser-based tool integrates GPL-licensedmeSpeak.js (a revisedEmscripten'd version ofeSpeak) and correspondences fromlexconvert to parseIPA phonetic notation and convert it to speech.

note

It was odd that this tool did not exist; the underlying components were free (as in beer and freedom) and readily available for years (eSpeak was Emscripten'd in 2011:speak.js) alongside clear demand (e.g., in 2013,r/linguistics andLinguistics Stack Exchange).

There was abookmarket for AT&T's Natural Voices demo, but the endpoint appears to be no longer available.

eSpeak, unfortunately, does not parseIPA phonetic notation directly, requiring the conversion assisted by lexconvert. Although the Emscripten'd version of eSpeak is somewhat large, two megabytes has become less noticeable as page sizes have increased over time. As a side effect, with no server-side processing and no automatic processing, privacy and security considerations were simplified (with the assumption that meSpeak.js is trustworthy).
