So, perhaps you can say that dolphins speak, and maybe chimps speak, and then we can even contemplate that bonobos speak (since they are very similar to chimps, but haven't been studied as much).
But dogs definitely don't speak, and neither do any other mammals that we've tried to test in this way.
Not to mention, there is another characteristic of human language that 0 animals can be taught, as far as we've tried - more complex structure, like "not (c and d)"
@toshitaka_szk in twitter. A Japanese dude can translate languages of birds and successfully did some experiences on it. And he is kind of famous.
And needless to say Hunger the dog[1]. Did this clear your humancentric brain?

Also this applies to limited intelligence human infant and mathematic immature dudes. So by your logic, those underintelligence human do not have consciousness. QED.
The Japanese research is much more interesting, and in a related comment I also cited a published article that proved that my claims, while fundamentally ok, are wrong in the details - animal calls are fundamentally simpler than human language, but some do show simple syntax.

I never claimed dogs aren't conscious, I only claimed they don't have language in the sense humans do. Infants also don't have language, but they learn it natively. All humans learn complex structures, even the mathematically illiterate, no idea where that came from. The only exceptions are people with serious brain disorders, and those people, indeed, don't "speak".
That, again, doesn't mean that they are not conscious beings.
I will freely admit that it actually refutes some of my claims - that's are actual example of simple syntax identified in several species.
Still, I believe it matches my broader point: there are a fundamental, measurable differences between human language and animal calls, with the latter at best showing only very basic structure, if any.

> Dolphin can understand sign language but dog dont. So ALL OF THEM do not speak.
Do you mean this? It is the same as saying that you dont understand Japanese and conclud that human can not speak.
Correct me if I am wrong. Or correct yourself.
