Voice update, most useful for non-Windows systems. Voice file building using Festival, Flite or eSpeak from the configure script. Compressing with Speex and Vorbis possible, but won't create useable voicefiles. Adds voicefont.c and wavtrim.c by Jörg Hohensohn. Also includes a script to generate talk clips.

+# A script to automatically generate audio clips containing the names of all
+# folders in a directory tree for use with the "Talkbox" feature available to
+# users of the Rockbox open source firmware for Archos MP3 players and
+# recorders as well as several other devices. Talkbox permits the device to
+# speak the names of the folders as one navigates the directory structure on
+# the device, thus permitting "eyes-free" use for those for whom the usual
+# visual navigation is difficult or simply inadvisable.
+#
+# Audio clips are captured and stored in wave format, then converted into MP3
+# format by a third party application (lame). If you execute the script,
+# passing it the top level of your music file hierarchy as an argument while
+# your device is connected to your PC, then the resulting audio clips will be
+# generated and stored in the correct location for use with the Talkbox
+# feature. Alternatively, if you mirror your music folder structure from your
+# PC to your Archos device, you can just run the script on the PC and then
+# update the files on your Archos with your usual synchronization routine.
+#
+# NOTE: If you don't already have them installed, you may obtain the Festival
+# text to speech system and several voices at:
+#
+# http://www.cstr.ed.ac.uk/projects/festival.html
+# http://festvox.org/festival/
+#
+# The most pleasant freely available Festival voice I know of is the slt_arctic
+# voice from HST at http://hts.ics.nitech.ac.jp/
+#
+# Known bugs
+# - This script generates talk clips for all files, Rockbox only uses talk clips
+#   for music files it seems.
+
+# Include voicecommon.sh from the same dir as this script
+# Any settings from voicecommon can be overridden if added below the following
