USAGE:
iisc <commands> <infile/text> [outfile] [options]

<>: Required, []: Optional

RECOMMENDED:
iisc /tts "The text you want to listen to"
iisc /tts input.txt
iisc /ttw "The text you want to convert into wav file" output.wav
iisc /ttw input.txt output.wav
iisc /ttm "The text you want to convert into mp3 file" output.mp3
iisc /ttm input.txt output.mp3
iisc /wtm input.wav output.mp3
iisc /mtw input.mp3 output.wav

COMMANDS:
/? Display this help
/e List all speech engines(popularly, voices) with index numbers
/tts Read text/file directly (text to speech)
/ttw Convert text/file into wav file (text to wav)
/ttm Convert text/file into mp3 file (text to mp3)
/wtm Convert wav file into mp3 file (wav to mp3)
/mtw Convert mp3 file into wav file (mp3 to wav)

OPTIONS:
-e <v> Read/convert text/file with a special speech engine
   <v> is speech engine index
   <v> = 0...?
   Default -e 0

Note:
You can display all speech engines with the command line "iisc /e" or
display the full info of a special speech engine with "iisc /e -e <v>".

-s <v> Adjust the speed of speech
   <v> is the value of speed
   <v> = 50...500.
   Default depending on the selected speech engine

-p <v> Adjust the pitch of speech
   <v> is the value of pitch
   <v> = 50...400.
   Default depending on the selected speech engine

-w <v> Write to file speed
   <v> is the times of the base speed
   <v> = 1...128+.
   Default -w 8

Note:
The maximum of <v> depending on the speed of your cpu.

-r <v> Sampling frequency of output file
   <v> is the value(kHz)
   <v> = 8, 12, 11.025, 16, 24, 22.05, 32, 48, 44.1
   Default -r automatic

-b <v> Set the bitrate in kbps
   <v> is the value(kbps)
   When the value of the option -r = 32, 48, 44.1
   <v> = 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320
   else
   <v> = 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, 144, 160
   For more information, see also the following table.
   Default -b 128

Note:
The relation of sample frequency to bitrate:
-----------------------------------------------------------------
MPEG-1 layer III sample frequencies (kHz): 32 48 44.1
bitrates (kbps): 32 40 48 56 64 80 96 112 128 160 192 224 256 320

MPEG-2 layer III sample frequencies (kHz): 16 24 22.05
bitrates (kbps): 8 16 24 32 40 48 56 64 80 96 112 128 144 160

MPEG-2.5 layer III sample frequencies (kHz): 8 12 11.025
bitrates (kbps): 8 16 24 32 40 48 56 64 80 96 112 128 144 160
-----------------------------------------------------------------

-m <v> (s)tereo, (j)oint, (f)orce, (m)ono or (a)auto
   force: force ms_stereo on all frames.
   auto: jstereo, with variable mid/side threshold
   <v> is the mode code
   <v> = s, j, f, m, a
   Default -m s or -m j depending on bitrate

-q <v> Mp3 quality level
   <v> is the level
   <v> = 0...9.
   0: Highest quality, very slow
   9: Poor quality, but fast
   Recommended:
   2: Slow, good quality
   7: Fast, ok quality
   Default -q 5
