flowm
Flite on Windows Mobile
flite file reader development "flown" or "flowm"
build up with cegcc menu example
type in text first
file selection.
good searching, bookmarking, replay (slower)
on screen word highlighting (default -- but optional)
wget data
interpretation of xml marked up programmes/channels
to get data and read it (like rss)
skinable
scriptable (through ssml)
Would be good to have voice choices
CG and VT if possible
computationally too expensive

TODO
* screen off option on main screen
* (makes it battery efficient)
* http://msdn.microsoft.com/en-us/library/ms838354.aspx
* http://forums.microsoft.com/china/ShowPost.aspx?PostID=4273639&SiteID=15
* no ending on ok
* fast backskip causes a crash
* long filenames badly displayed
* added ES_AUTOHSCROLL to field
* more control in play dialog box
* choose voice
* display pronunciation/text expansion etc
* allow waveform saving in play
* BM in play text not play file
* normalize volume across voices (boost cg ones)
do something with silences to optimize speed
back/forward over restarts seems to over skip
keyboard accelerators (at least ctrl-q)
can't stop BM "1982 was ..." would take a little time
get rid of title bar on open/savefile box
tgps doesn't have the problem
"save" grey out if nothing to save
some content on the startup screen
logo plus play or play_file buttons
CAB installation (with lcab)
no evidence lcab works for mw yet
http://nedge2k.com/cab-o-matic ??
cut and paste from other apps
file position over app restarts
and voice selection
make it not look like a .net app
screen off after n seconds of play
previous files selection in file selection
button support (no ending on ok, stop continue etc)
screen rotate
icons rather than text on buttons
play/stop as one button
autorepeat on forward/back
scroll wheel (volume or forward back or faster/slower)
dll version (for voices too) would be good
progress bar
word highlighting at play time
a talking head example
prc files
Inertia based file listing
Inertia based position finding in file
0.6 19th
5.01meg with kal, awb, rms and slt
with screen off, 40 minutes of running used 6% of battery
(kal might be different from cg voices)
a benchmark in flowm so I can find out the speed of the machine
GetSystemTime (but no milliseconds)
if #define double float in cst_mlsa.c
Tilt kal 503.5 16.0 31.47
awb 44.3 50.0 0.89 but it *is* fast enough (sort of)
rms 48.9 54.0 0.91
and a wee bit faster again if wifi is turned off
Tilt kal 503.5 15.0 33.56
awb 43.7 69.0 0.63
rms 48.3 72.0 0.68

awb 43.7 68.0 0.64
kal 48.3 70.0 0.68
dll version (for voices too) would be good
some content on the startup screen
- forward/back utterance
forward/back paragraph/chapter/file
quick back skips causes crash
- try out PowerPolicyNotify(PPN_UNATTENDEDMODE, 1); during play
http://channel9.msdn.com/wiki/mobiledeveloper/powerpolicynotify/
* do file pos as percentage
progress bar
get rid of title bar on openfile box
* cg voices give click at buffer change
good enough on 2755 (rms and awb order 13/8K)
* get a 641K awb voice (and others)
720K actually with 13 params
* good enough for tilt (#define double float)
* multi-voice version
* made audio_streaming_info with min_buffsize
file position over app restarts
icons rather than text on buttons
play/stop as one button
make it not look like a crude app
cut and paste from other apps
more control in play menu
display pronunciation/text expansion etc
word highlighting at play time
a talking head example
keyboard accelators
ok should background it not stop it

hp2 9:54 awb 8k 2755 (black clip) 98%
backlight off after 2 minutes
10:30 fp 29500 79%

using threads so that stop works
can't share alloced memory over threads
add streaming synthesis
stop works
need to select position in file
nees to save position in file for continuation
pause and continue
stop it from going to sleep (but do screen blank)
8K awb 1139896
16K awb 2227760
could be 641K if order 18 and get rid of std in statics
Put back in the Play_thread. With a large buffer size, it sort of
works (spool vs streaming)
Tested under
Ipaq 3635 WinCE 3.0
Phraselator 2 Windows CE 4.20 (HPC?)
gives an error at exit time (maybe the others do too ..)

TTS from a .txt file
display tokens in window as we go
redo the menus and forms layout
Still very basic though.
stop doesn't work bacause things don't get back to the event loop.

have windows, a dialog box with a play and editable text box
spent ages working out how to program in WinCE but seems to work now
1st Jan 2009
0.1
play_wave(w) does the right thing
au_wince.c seems to work
moved to mingw32ce version
added a .rc resource file and tidied up configure.in
moved to cst_file_wince.c rather than cst_file_cegcc.c (deleted)
fixed bugs in cst_file_wince.c
type in box and audio out
want flite.dll cmu_us_kal_diphone.dll usenglish.dll maybe
have them loaded (so voice isn't in flowm)
Need examples/tutorial on building an app with inputs, defaults, options
file loading display etc.
streaming synthesis? (and call back)
0.0
compiled flite with message box displaying number of bytes in
synthesized waveform. Synthesis seems to work, WCHARs support is
necessary
