Siri Protocol Cracked
First time accepted submitter jisom writes with something that will probably not be working come morning. Quoting the source: "Today, we managed to crack open Siri's protocol. As a result, we are able to use Siri's recognition engine from any device. Yes, that means anyone could now write an Android app that uses the real Siri! Or use Siri on an iPad! And we're going to share this know-how with you." Basically, Siri sends the data to the processing server using non-standard HTTP extensions. Of note is that the audio is encoded using Ogg Speex. -
Codec2 — an Open Source, Low-Bandwidth Voice Codec
Bruce Perens writes "Codec2 is an Open Source digital voice codec for low-bandwidth applications, in its first Alpha release. Currently it can encode 3.75 seconds of clear speech in 1050 bytes, and there are opportunities to code in additional compression that will further reduce its bandwidth. The main developer is David Rowe, who also worked on Speex. Originally designed for Amateur Radio, both via sound-card software modems on HF radio and as an alternative to the proprietary voice codec presently used in D-STAR, the codec is probably also useful for telephony at a fraction of current bandwidths. The algorithm is based on papers from the 1980s, and is intended to be unencumbered by valid unexpired patent claims. The license is LGPL2. The project is seeking developers for testing in applications, algorithmic improvement, conversion to fixed-point, and coding to be more suitable for embedded systems." -
Format of Choice for a Legal, Free, Audio-eBook?
audioAuthor asks: "Let's say I have a recorded audio-book (no music, just speech), which I want to share with the world. What format should I use to distribute it? Main requirements would be: 'Everyone is allowed to redistribute it without any restrictions" and "Usable as widely as possible'. I have been thinking of MP3, Ogg Vorbis and Speex. MP3 would be really nice, as it's usable almost everywhere, even without a computer, but it has licensing problems which I don't quite understand. Speex is free and designed for speech, but it's not widely supported at the moment. I think that Ogg Vorbis is currently better supported than Speex, and also free, but not designed for speech and would take more space to achieve same quality. So what do you say? Which one of these should I choose, or are there other formats to consider?" -
Missed Your Flight? linux.conf.au 2003 CD Out
lpontiac writes "The official conference proceedings CD from linux.conf.au 2003 is out! It features talks (in Ogg Speex format) and papers from the likes of Alan Cox (Linux), Andrew Tridgell (Samba), Rasmus Lerdorf (PHP) and more. There's a list of mirrors on http://conf.linux.org.au/, both to ISO images of the whole shebang, and copies of the CD contents so you can download individual talks." -
Speex Goes 1.0, Xiph Goes 501(c)3
Emmettfish writes "Hey, folks! We've posted an announcement this morning; Speex (the free and open voice compression codec by Jean-Marc Valin) has gone 1.0, and the Xiph.Org Foundation is now officially recognized as a charitable non-profit organization by the IRS. Donate to help us write more Free Software and get a tax break. Thanks!" -
Speex Joins Xiph To Bring Free VOIP To The Masses
xercist writes "Xiph.org has added a new project to their plate of goodies- Speex. Speex is an audio codec specifically for, you guessed it, voice. It has integration with Xiph's OGG container, but is mainly being used right now for VOIP. There is currently an XMMS plugin available, and is also supported by LinPhone, OpenH323, and GnomeMeeting. Asterisk PBX is working on adding support. This is not a new project -- Jean-Marc Valin has been hard at work writing the codec for quite a while now. However, Jean-Marc is now a full-fledged member or the Xiph.org team, and in celebration, Speex beta one is being released. Xiph.org has brought you (or is currently working on bringing you) Vorbis, Tremor, Theora, Tarkin, Icecast2, cdparanoia, now Speex, and, of course, the Moaning Goat Meter. This is a LOT to do, so please donate to show your support."
