There is Google's Automated Speech Recognition (ASR) which they have
used for their automated captions system in YouTube since 2009:

Not sure they let you access that piece alone so you might have to
upload the media to youtube first and then ask for captions to be generated.

Hi Esther,
That's interesting, I've never heard about it before. I imagine you're right
that the logistics of creating software that could reliably convert speech to
text without training, would just be impractical.
Cheers,

Hi Donna and Aman,
I think it's not that what you're looking for doesn't exist, but that there
aren't commercially available solutions. Back in 2005-2006, shortly after the
original MacVisionaries list got started, there was a podcast search engine
named PodZinger, later renamed EveryZing. I think it must have been running a
version of the continuous speech recognition system that the company
responsible for this effort, BBN, started developing about a decade earlier.
At that time the number of broadcast podcasts was much smaller than now. The
PodZinger search engine let you type in a phrase or set of keywords, and then
it would pull up a match to identified podcasts, and even estimate the time the
phrase occurred within the podcast. It was sort of like doing a Google search
for podcast audio content, and pretty impressive. You had to type in enough
words in the search term to identify the context, because just like a Google
search you'd get a short section of matched content, but you didn't have to
really type more than you would for a Google search. I think this service was
only around for a couple of years.
Probably this was an outgrowth of Department of Defense funded research. You
ca probably do a web search to read more details. I don't know of anything
like that exisiting commercially, and you'd probably need to have a huge
training set (like the database of Siri users with different accents and speech
patterns) to train the software.
HTH. Cheers,
Esther

Hi, Aman,
Unfortunately, it was the latter. I kind of didn't think that there was
anything that could do this, but I figured if it was out there, someone on this
list would know about it.
thank you for responding, if nothing else, it's good to be sure that what I was
looking for doesn't exist.
Cheers,
Donna

Hi, Donna.
If I may ask, what sort of speech are you looking to convert? That is,
are you looking to convert speech from a speaker over which you have
control, or recorded speech from a person who is willing to read
training text? Alternatively, are you looking to convert speech that
is, for example, broadcast, recorded from a speaker who will not train
the software, or some other speaker over which you don't have any
control? The first is fairly simple. If you can have the speaker
record his/her/its training speech on to a digital recorder, there are
programs which you can train using that recorded speech and they will
then recognise that particular speaker's recorded voice fairly well.
If, however, you're after the second, for example, transcribing a
broadcast recording, I know of nothing that will produce an acceptable
transcription without human input. If you find such a thing, however,
I, along with quite a few other people, would be overjoyed, this,
particularly in real-time, would be a godsend to those of us with bad
hearing. If you find anything like this, then, please let the list
know.

Hello all,
Does anyone know of any software that will take speech, not dictation but
recorded speech, and converted to text? It could either be mobile software
or software for the Mac.
Thanks,
Donna
