transcriber-wrapper 1.2.1

A wrapper of well-known translators that transform text into its phonetic transcription

Transcriber Wrapper

Inspired by Phonemizer, this a simpler version focused in transcription applications that work with IPA (International Phonetic Alphabet). This works like a wrapper which is responsible to call a back-end application, let's say espeak-ng. It adds some features on top of it like with stress option.

Supported back-ends

• eSpeakNG
• Festival Speech Synthesis System

Usage

You need to install espeak-ng and festival on your operational system. See Dockerfile.dev as an example. After that, you can create a transcriber and then use it in your logic:

from typing import List

import transcriber_wrapper

# The standard language is "en-us"
# The standard back-end is "espeak"
transcriber_en_us = transcriber_wrapper.build_transcriber()

def do_the_thing(words: List[str]) -> List[str]:
    return transcriber_en_us.transcribe(words)

Development

Executing commands directly on the binaries

After building the remote interpreter service, just enter in it:

docker-compose run remote-interpreter sh

You must be at /usr/bin/. Then try one of these below.

eSpeakNG

Check out these links:

• Supported Languages
• Command Line User Guide

Some sample commands:

espeak-ng "Hello my friend, stay awhile and listen!" -ven-us -x --ipa -q --sep=_
espeak-ng "Curiosity" -ven-us -x --ipa -q --sep=" "
espeak-ng "If you will not bow before a sultan, then you will cower before a sorcerer!" -ven-us -x --ipa -q
espeak-ng --voices

Festival

You can execute festival --help to get a list of what you can do through what the festival developers call "Shell API" (see more details here).

You can use the script festival.lisp to get the computation from a given word, some samples:

WORD=something festival -b /app/scripts/festival.lisp
WORD=theoretically festival -b /app/scripts/festival.lisp

What you can do is just type festival and then start its command line prompt. From there you can do the following for example:

# It will list voices available
festival> (voice.list)
# Default voice
festival> voice_default
# This won't work with our Docker image, but if you are on your ubuntu/debian machine, it may will
(SayText "Can someone refactor festival to be writen in Python with a friendly API?") 

Updating pipenv dependencies

If you update Pipfile, you can issue the following command to refresh your lock file:

docker-compose run remote-interpreter pipenv update

If you'd like to add a new package, let's say a production one:

docker-compose run remote-interpreter pipenv install pyparsing

Don't forget to update your service!

docker-compose build remote-interpreter
