translation shirt (well, apron) – offline and realtime, and fashionable AF (ok j/k on the latter)

tada!

Video demo πŸ™‚

You can see the kind of mistakes it makes —

The translation package (argostranslate) really wants proper grammar, while the transcription (vosk) package does not care at all… I did try a vosk model that preserves casing, but it was so slow to run that it would just miss audio entirely which was worse.

Also I couldn’t get Chinese or other languages to work with argostranslate, only Spanish (it would just output the input text instead of any Chinese characters). I wonder if I messed something up with my install.

one morning later… english speech to text, then translated to spanish — in realtime & offline

we live in the future!! this is some crazy stuff

here’s a short/random video demo (needs audio on)

XD;

The translation engine really wants proper grammar (e.g. capitalization and punctuation), and the transcription engine really doesn’t care about all that nonsense.

So now I’m working through grammar checkers.

attempts at grammar fixing

I found a promising library that unfortunately turned out to just be a wrapper around an API service, a.k.a. doesn’t function offline T^T It works quite well.
The other two options: language_tool_python, which is a wrapper around the grammar/spell check that libreoffice uses. It’s more rules-based. And then some random transformers model.

Here’s the results. The random transformers model doesn’t perform as well as the (company, gingerit)’s fix and is rather … unpredictable. The language tool doesn’t perform great either, but it’s relatively fast. And then we have gingerit, which is slow purely b/c it’s an online model (and not a fair comparison in that case for accuracy).

I also show how fixing the grammar/spelling matters when then putting it through argotranslate.

quick experiment: python library for real-time offline translation (english to spanish)

wow, pip install argotranslate, and the offline translation just works

and it works fast

Seems plenty fast to me to actually use in real time!

The library is: argos-translate

The code is straight from their github.

https://github.com/argosopentech/argos-translate

code

import argostranslate.package
import argostranslate.translate

from_code = "en"
to_code = "es"

# Download and install Argos Translate package
argostranslate.package.update_package_index()
available_packages = argostranslate.package.get_available_packages()
package_to_install = next(
    filter(
        lambda x: x.from_code == from_code and x.to_code == to_code, available_packages
    )
)
argostranslate.package.install_from_path(package_to_install.download())

# Translate
translatedText = argostranslate.translate.translate("Hello World", from_code, to_code)
print(translatedText)

 def trans(phrase):
   ...:     return argostranslate.translate.translate(phrase, from_code, to_code)

trans('I think it will be more than fast enough for real-time use')
>>> 'Creo que serΓ‘ mΓ‘s que lo suficientemente rΓ‘pido para uso en tiempo real'

other tools to check out

(haven’t bothered yet)

https://github.com/OpenNMT/CTranslate2

according to https://skeptric.com/python-offline-translation “Argos Translate is a more complete solution, is easier to get set up, and is substantially faster. However Marian Machine Translation gives better translations, supports more languages, and better supports batch translations.”

Note: The tool will fail if the punctuation and capitalization is not correct however.

back story

The idea is to create a translation t-shirt. So take the following project one step further:

The code / instructions are here: https://github.com/ZackFreedman/DeepgramSubtitleHoodie /

(It looks like he used a $75 touch screen (“stretched bar display”), I guess he had it lying around ?? I’m not sure that’s where I want to be swiping around on myself lol) (but maybe that is the cheapest?)

Basically just pipe output of the real time speech to text tool to the translation tool,

Then wear an apron with the screen built-in. So I can speak and have the apron-tablet auto-translate.

Actually, it could have a fold-out mirror. So if there were also vision problems, I could look down at the mirror and just speak the translated text out loud XD;

i would feel like such a nerd

actually though this would be a neat tool for traveling to another country,

waiting for google translate lag (both in terms of phone processor and 4g availability) is a pain

if I am just using stuff I already have, maybe the next step is installing linux on a switch — that’s the closest to a portable screen I have at the moment… (I was playing FFXII really intensely but have since lost interest, I think due to not being sure what direction to take the game)

ALTERNATIVELY. A youtube commenter suggested — I could make a persistence of vision hat, and that would be pretty darn cheap haha.

And… need a glare / matte screen apparently. See 13:07.

rambles

I’m not sure how I feel about this, it might reduce my motivation to learn languages. I guess once I make real moneys I would like to pay for Spanish lessons or something similar. @__@ (And Chinese lessons for that matter). I’ve also discovered though that maybe I’m not the greatest at learning languages? I have no idea.

Life feels weirdly short and long. I was too busy recovering from crisis in my mid-20s to have too much of a quarter life crisis I guess. But now that I am emerging out of one crisis, I feel a bit adrift in terms of identity and what I’m trying to do with my life.
