Let me put into evidence a portable Text-To-Speech source environment already ported to Palm and Linux and Windows CE.
On the chart nothing is forbidding porting to Sony PSP.
Here is the project, with docs and sources

RE-EDIT:

(previous address wrong, sorry)

I've many ideas in robotics but more on hardware expert than on coding, so I'd like to join someone expert for setting up and run this Text to Speech on Sony PSP .

Thanks for attention, interest and of course co-operation.

Hi.
The link doesn't appear to work.
Doe it still work for you?

[mypspdev]

I'm sorry, new correct URL show in original post.

i have only this to say ...

If you're into robotics, you probably alreay have a lot of microcontrollers
doing things. Have you looked at the SPO-256? Out of production, but still out there (can provide links).
There is also the Speakjet if you have some money to spend on it.

Both of these devices could be controlled serialy by the PSP, if the PSP
must be involved.

I think I'll take a look at it. There are lots of uses a text-to-speech library could be put to. A handy one would be a file reader for people who can't be stuck looking at the PSP for hours at a time - like having it speak a novel while you're driving. Books on tape the cheap way. :)

Thanks J.K.!
Me too, I do not see Speech Recognition on 32Mb RAM only...
But I know some works on portable done even if without floating point coprocessor.
PSP may be is not able (slim one?).
I have prepared 3 cygwin directories on my hard drive root and renaming them according to usage, I could compile C programs.
- one is for native Windows-Intel686 .exe
- one is for psp: I found on the web a full-in-one 155Mb cgwin ready to work for PSP with last psptoolchain: I avoided loosing time with ./toolchain.sh...
- one set up for working with NanoDesktop: may be you know it (0.3 version, with vision recognition OpenCV embedded)

I am not yet so expert to change makefile and others for FLITE to be compiled under cygwin/psp : I was able to produce exe for Windows-Intel686: it works, not high quality like SAPI but it works fine: wav or speech are produced.

I hope you could be successfull compiling Flite for PSP and teach all of us how-to-do.

Thanks again!

Any progress?
I'm still in trouble adapting compilation, before working on output fileio or .wav player srcs.

IMHO the TTS audio quality of 'flite' and other similar PDA text-to-speech is rather poor. The main use of TTS on a PDA is for dynamic changing data, or for systems with small memory storage.
Listening to an on-the-fly 'flite' TTS playback of a long book may get irritating. The PSP is already a great media player.

For TTS books-on-tape, I recommend running it through a PC based TTS package (many available, some with GigaBytes of voice fonts for greatly improved voice quality). Then take the results, save as .MP3 and copy to your PSP (works with homebrew or non-homebrew PSPs too)
At a moderate bit rate .MP3, your memory stick can hold a long book. The PSP is already a great media player. For media creation, horsepower-wise, a PC wins hands down.

do we have a library for the usb camera microphone?
I didn't know there was a mic in it.
I didn't know we could access it.

The problem with the Socom compatible DIY jobs is that no micrphone
works anywhere near as good as the genuine Sony one.
I don't know why, although I have stripped one right down to the
microphone stalk, and there's still the same two wire leaving that.
Not prepared to wreck it completely since over here in Aus we have to buy
Socom to get it.

[mypspdev]

[J.F.]

I'll have to keep an eye out for a chance to pick up the camera then.

Yeah, that's great news, only not in my country yet.. might try eBay, thanks!

[mypspdev]

that is why it's time to put our hands on the Skype APIs to develope a PSP VoIP, finally videoconferencing......

[mypspdev]

Good day to all!
I'm just back from August holidays, and soon I'll restart working (or joking?) with PSP SDK.
I'd like to have, if any, news of Flite porting to PSP....
Thanks a lot to all replies

[J.F.]

Been busy... haven't had much time to work on it. Maybe this weekend I can make some time.

[mypspdev]

Hi J.F.!:

I've been able to compile with psp-gcc all .c sources and libraries *.a have been created from /lang/ directories.
Now I'm working on /src/ sources. Again all objects has been succesfully compiled, but /src/audio/au_psp.c that must be modified from original (palmos?) and /src/utils/cst_file_psp.c that must be modified (from wince?), according with /include/cst_audio.h and /include/cst_file.h.

Flite Audio -> PSP Audio
Using pspaudiolib.c something could be related, up to my analysis:
audio_open_psp -> pspAudioInit
audio_close_psp -> pspAudioEnd
audio_write_psp -> pspAudioOutBlocking

with all added set-up of variables used by Flite.
One structure is appearing to be well understood: in Flite /include/cst_audio.h the structure ad is defined, with ad->sts value that has to be initialized.

Whenever you will have time to analyse in deep the audio and IO part of Flite->PSP we could share and update results.

Bye Bye

Audio Porting of Flite to PSP (au_psp.c):

at the end we are going to port audio open/close/write without using audiolib:

OPEN:
int channel = sceAudioChReserve(PSP_AUDIO_NEXT_CHANNEL, PSP_AUDIO_SAMPLE_ALIGN(sampleBufferSize), PSP_AUDIO_FORMAT_STEREO);

CLOSE:
sceAudioChRelease(channel);

WRITE:
sceAudioOutputPanned(channel,PSP_AUDIO_VOLUME_MAX, PSP_AUDIO_VOLUME_MAX, sampleBuffer);

The rest is to initialize the structures and variables used by Flite in au_psp.c (as copied from others).

J.F.: we could work on it.

Thanks, next good news, hope

Frankly, I got busy on other things and forgot all about it. :D

By the way, flite's new address is: http://www.speech.cs.cmu.edu/flite/

[coolkehon]

so are you going to do it?
