hearing the "s"
why when saying: "Tu es une femme" you pronounce the s of the "es", but when saying: "Je suis une femme" you do not pronounce the s of the "suis" ? are there any cases where the s of "suis" before a vowel will be heard or you sould never pronounce it in any case ?
It's called liaison in French, you can read this wiki article to learn more: http://en.wikipedia.org/wiki/Liaison_(French). I think the rules are generally complicated for a non-local so you should expose yourself to everyday spoken French like watching french movies or television and videos on youtube. Myself I download French news and listen to it daily while walking the dog, it helps immensely just to immerse yourself as much as possible.
Also this is a good site: http://tatoeba.org/eng/. It has full sentence translation and some contain audio with a native dictating the sentence. Myself I use to "liaise" the es and notice that it wasn't done by the native speaker.
I would take Duo's pronunciation with a grain of salt - doesn't always seem to be correct. For instance, she pronounces the "s" sound in "est-il" - I don't believe that is correct, I think the "s" should be silent and only the "t" pronounced. For your above Qs, I would say the "s" is silent in "Tu es une femme." but pronounced like "z" in "Je suis une femme."
actually in "Tu es une femme" you pronounce the s(z) of the "es", and when saying: "Je suis une femme" you do pronounce the s(z) of the "suis", see http://french.about.com/library/pronunciation/bl-liaisons-r.htm ; if you really need rules, the whole "liaison" thing being about euphony (souding good)
It is very simple : if you intend to speak French right, you must use liaisons that are necessary to a nice flow where two vowel sounds should not conflict: 'je suis(z) une femme'. However, native French people pay less and less attention to 'good' speaking. Journalists or politicians or other professional speakers are not always doing it right either. You seldom hear 'trois (z) euros'. Too bad!
In my experience, in almost every case where a terminal "s" or "t" is followed by a vowel (without a comma or other punctuation to interrupt it), the sound carries over to the next word. I agree with CSI, I have never heard the "s" in "est-il" pronounced, but the "t" is.
Yes, I wouldn't put too much stock in the Duolingo computer voice. I would not pronounce the s in es or est no matter what came after, and would pronounce the last s in suis if the next word started with a vowel. Like a z, as csi says.
I discovered a similar situation with 'et' and 'est". L'homme et un chien, (silent t); L'homme est un chien, (t pronounced). Get it wrong and instead of talking of the man and his dog you will say 'the man is a dog', and you risk getting into trouble.
I agree with what most people here say, but I'd add that speaking French has a lot to do with what "feels" nicer. Sentences that flow together without too many rough stops and changes are generally more likely to be correct.
you do pronounce de S but together with the next vowel as if it is one long word because you do a liaison usually when it is followed by a vowel you do pronounce it
I don't think you pronounce the s. My french teacher didn't, and he is French, lived in Paris for 17 years and studied French at a French university.
When in the situation of a liason, when after 'suis' you have a vowell, then the 's' is pronounced but as a 'z' sound.
When the next word starts with a vowel, you pronounce the last thing at the end of the previous word.
Actually, correct pronunciation is the opposite of what Duo does here. Never pronounce the "s" in "es" and most often you so pronounce the "s" of "suis" before a vowel. Although, my understanding is that rules of liaison in French are changing and often it is up to the individual speaker--to use or not to use liaison.
The "t" at the end of the conjunction "et" is never pronounced, nor there is liason with the next word, ever. This applies only to "et".
just wondering? any native speaker here that really pronounces the -s in plus tard? I've never heard someone in France doing that.
neither do I, knowing french for a long time. however the duolingo lady really says 'plussss'
