eSpeak Phonemizer

Uses ctypes and libespeak-ng to transform text into IPA phonemes.

Installation

First, install libespeak-ng:

sudo apt-get install libespeak-ng1

Next, install espeak_phonemizer:

pip install espeak_phonemizer

If installation was successful, you should be able to run:

espeak-phonemizer --version

Basic Phonemization

Simply pass your text into the standard input of espeak-phonemizer:

echo 'This is a test.' | espeak-phonemizer -v en-us
ðɪs ɪz ɐ tˈɛst

Separators

Phoneme and word separators can be changed:

echo 'This is a test.' | espeak-phonemizer -v en-us -p '_' -w '#'
ð_ɪ_s#ɪ_z#ɐ#t_ˈɛ_s_t

Punctuation and Stress

Some punctuation can be kept (.,;:!?) in the output:

echo 'This: is, a, test.' | espeak-phonemizer -v en-us --keep-punctuation
ðˈɪs: ˈɪz, ˈeɪ, tˈɛst.

Stress markers can also be dropped:

echo 'This is a test.' | espeak-phonemizer -v en-us --no-stress
ðɪs ɪz ɐ tɛst

Delimited Input

The --csv flag enables delimited input with fields separated by a '|' (change with --csv-delimiter):

echo 's1|This is a test.' | espeak-phonemizer -v en-us --csv
s1|This is a test.|ðɪs ɪz ɐ tˈɛst

Phonemes are added as a final column, allowing you to pass arbitrary metadata through to the output.
