 Hi!
 Thanks for you remarks. New (slightly corrected) version you can find 
 at:

 sd_txt2pho knows basic parameters (gender, samplerate) of six known to 
 me German voices and automatically loads all voices found in path, 
 giving arbitrary names. So first found male voice (in your case 'de2') 
 will be default.
 In configuration file you can only rename voices, not enable or 
 disable.
 It should be parameter in configuration to select which voice (voices) 
 will be default, for example:

 default voices = de6 de7

 What you think?

 At now you can look at beginning of GerSpeaker class in sd_txt2pho.py 
 file and move de6 to first position in _german_vlist.

 I added logginng used audio method, so you will be able to check it 
 near top of log file.
 For today audio is maximally simplified (it selects 'pulse' driver if 
 you had 'pulse' in main speechd config or 'ao' if you have something 
 else), but it will be changed in next version (I have working audio 
 selector in my milvona module, so I must only rewrite it in Python
 and add extra parameters to Spda class initializer).

 Wrong! It will break spelling mode of module!
 It was bug in Phonetizer class, now you won't hear blank echoed. Also 
 there is new parameter 'announce blank' in configuration (may be someone 
 want to hear 'blank' when pressing space).

 Yes of course!
 But I think the Latinizer class must be improved first, as many 
 improvements will be common for most languages, not only German.

 Answering your second mail:

 How long time? As I mentioned previously, this time will be shorten to 
 minimum, but it's not trivial (some constructions working in C does not 
 work properly in Python, especially subprocess.Popen behaves very 
 strange). In log file you will have lines starting from 'Preparation 
 time' showing time consumed for preparing each part. If this time is 
 same as you hear, simply be patient, it will be corrected as fast as 
 possible. If the real time is longer, check your audio driver.
 Due to bug #866 in pulseaudio it's not possible to close connection 
 immediately after draining internal pulse buffers, so extra silence was 
 added instead. Is it the reason?
 Another possible reason: you have pulseaudio installed, but in 
 speechd.conf you selected another driver. In this case current version 
 of module
 will use libao with internal pulse driver, which is worst thing and you 
 should simply wait for next version.

 Strange - I didn't see this effect. It was bug in Latinizer (corrected 
 - it was spoken 'hello world' instead of 'punkt hello world').
 In command line:

 spd-say -o txt2pho '. hello world'

 produced speech as above. Also I tried to read your mail with Orca and 
 Firefox - without problems.

 In log file you will have input data and message logged. As you can 
 enable/disable logs on the fly simply changing 'enable log' parameter in 
 configuration, please send me fragment of log file with string producing 
 bad output.
