I'm looking for a translation software, or website, that accurately translates entire sentences and paragraphs from English to Hebrew, without grammar mistakes or funny language usage. Anyone know of something that can help me?
While Yossi Rozenman is right in that there is no software that accurately translates sentences with no grammar mistakes or funny usage, I am partial to Google Translate, located at translate.google.com and with applications for Android and iPhone.
There's no such software or website. The only way to get an accurate translation is using a professional translator.
I tried a little experiment, and inserted text into google translate, and then had Bablyon reverse the translation. I did the same again in reverse. You can then compare the two translations, until you find something good. :) Also helps you learn the language.
In the end however, you will need a professional to translate it properly.
No such amazing software, but you may wish to try http://context.reverso.net/translation/ It is nice for translating short phrases.
the best software for english to hebrew translation is Babylon - http://www.babylon.com/welcome/index.html?affID=109100
