[Flightgear-devel] Text-to-Speech system, was: New release
Hi all, On Thursday 23 December 2010 21:27:19 Stefan Seifert wrote: Makes me wonder how difficult it would be to fully integrate festival into FlightGear. Not using some external program, but linking the library and shipping appropriate voice files. Stefan in this context I would like to point you to a text-to-speech library developed by the Carnegie Mellon University: Flite (festival-lite, see http://www.speech.cs.cmu.edu/flite/). It can be embedded in existing code quite simply, requires no additional dependencies, is thread-safe and distributed under an X11-like license which should (please correct me if I'm wrong) be compatible with the GPL...

On the other hand, one could certain do a better voice for ATC as the vocabulary is very limited in this case. The voice quality of flite is a) good enough for ATIS/AWOS (which in real life are often synthesized and artificial-sounding), and b) better than anything that is likely to be achieved anytime soon using the current code that pastes together snippets, and c) infinitely better than what is in the git repo at the moment, which is no ATIS at all. Also: The cpu workload of flite is pleasantly small. On my machine it takes something like 60 milliseconds to render a typical ATIS message. Furthermore -- if properly implemented -- this could be done in a separate thread, so that in a modern multi-cpu machine no time at all would be taken away from the main simulation. To say the same thing another way: I have an investment in the existing snippet-based system, but I would be well pleased to see it replaced by something better. -- Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
[Flightgear-devel] ATIS, AWOS, synthesis, runway -in-use, et cetera

As I see it, if there are N players, there need to be N+1 processes, namely one for each player plus one for the ambiance. The ambiance includes not just things controllers say but also ATIS/AWOS, pilot controlled lighting, etc. etc. etc. It would be super-cool to have one player turn on the pilot controlled lighting and then have *all* the players see the lights come on. ATIS and runway lighting are also tied up with the more general concept of runway-in-use, which interacts with reversible ILS. Right now FG allows simultaneous approaches to both ends of a reversible ILS, which is just ludicrous from the radio-physics viewpoint as well as the pilot's operational viewpoint. The patch to do something sensible with reversible ILSs has been available for a couple of years. !00% of the pilots who have commented on it consider it an improvement. http://gitorious.org/~jsd/fg/sport-model/commits/navaid-repairs/ -- Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
[Flightgear-devel] Minor menu renaming
Hi Guys, I've been updating The Manual for the upcoming release, including updating the command reference to include the changes to the menus. I came across a couple of menus which seemed mis-named, and for which I've just committed some changes. Specifically: 1) The AI menu had AI prefixed on all the menu items, which seemed redundant given that all these menu items exist under the AI menu. I've made the following changes: AI Options - Traffic Options AI Formation - Wingman Controls AI Tanker - Tanker Controls AI Carrier Options - Carrier Controls AI Scenario Select - Scenario Select 2) Moved Common Aircraft Keys up from the Key References section, and renamed it to Aircraft Help, given that it usually includes more than just key bindings. I think both these changes are pretty uncontroversial and reflect much more closely the dialogs themselves, hence I've just gone ahead and committed the changes. If anyone really objects, or has a better suggestion, I'm happy to back them out. Happy Holidays to everyone! -Stuart -- Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
