Result mismatch Google Translate

[joeperpetua]

Hi guys, hope you are doing well.
I know that you are pretty busy working on v3 and may are already aware of this already, but just in case I open this issue.

When using the GoogleTranslate service, the translation is different from what we get in the website/app:

• Source: fr (auto)
• Destination: en
• Text: Sincèrement navré de ne pas avoir répondu à vos messages plus rapidement, lorsque le dossier est transmis aux développeurs, nous n'avons temporairement plus de visibilité dessus.

[1] Google translate result:
Sincerely sorry for not having replied to your messages more quickly, when the file is transmitted to the developers, we temporarily no longer have visibility on it.

[2] translatepy result:
Honestly sorry not to have answered your messages faster, when the file is transmitted to the developers, we do not temporarily have more visibility on it.

Any ideas of what/why could be this caused? I actually tried changing the session header as per #79 but it did not have any effect on the translation result.

TranslationResult(service=Google, source=Sincèrement navré de ne pas avoir répondu à vos messages plus rapidement, lorsque le dossier est transmis aux développeurs, nous n'avons temporairement plus de visibilité dessus., source_language=fra, destination_language=eng, result=Honestly sorry not to have answered your messages faster, when the file is transmitted to the developers, we do not temporarily have more visibility on it.)

Try to use GoogleTranslateV2 class as workaround: #22 (comment)

Thanks, that works well!
So I understand that the GoogleTranslate service defaults to GoogleTranslateV1, right? I assumed it used the V2 by default 😅

Yup for now GoogleTranslateV1 is tried first

translate/translatepy/translators/google.py

Lines 78 to 86 in 1033e1f

	self.services = [google_v1, google_v2]
	def _translate(self: C, text: str, dest_lang: typing.Any, source_lang: typing.Any) -> models.TranslationResult[C]:
	for service in self.services:
	try:
	return service._translate(text, dest_lang, source_lang)
	except Exception:
	continue
	raise ValueError("No service has returned a valid result")

The reason is that V1 should be the one used on the website, but we can't generate the right tokens for now : #22 (comment)

@Animenosekai so v2 better than v1?

Well without reverse engineering the token generation, yes (maybe?)
