Viavoice runtime code#
(The code in WAIT_OBJECT_0+1 section in SDIEarconThread was used for this heavy work.) So, I have to fall back on DirectX itself. Because I can't finish processing in 70ms, some notifications are lost and the sound coming out of my earphone is dreadful. 70ms to lock the buffer and copy the data between two notification points to A3D source buffer, if I want to achieve best positioning effect. (It took me quite a while to investigate into the DirectSound Buffer ^o^)įrom the picture above, you can see that I have only approx. The illustration below describes what the DirectSound Buffer looks like when a specific notification point is encountered. When you play DirectSound Buffer, the play cursor will erase the data it's read. For Earcon, I found something really interesting and, well, frustrating indeed. Possibly due to the evaluation version of ViaVoice TTS SDK, I found out that eciSpeaking didn't work! So, I added one more thread to each Speech object, only to find I can't achieve actual Pause function on the Speech object, because ECI (API provided by ViaVoice TTS) does not support thread-reentry. Traverse the object list to delete hSpeech2 and hEarcon2 return 0

Please refer to "MIDI Specification" and "MIDI File Format" for detailed information on them.įor more information about SDI, see sdi_readme.txt and SDI v1.0 document in the zip package. Some knowledge about MIDI and MIDI files is highly recommended.Refer to Play/ParseNotation and PlaySegment to see how to use Earcon correctly. Earcon is relatively more robust than Speech, except for its restrictions on data.You can achieve "sound animation" by using them. Get/Set Position/Volume are always safe, because they are handed over to A3D or DirectX internally.So, please make sure there are intervals between operations. In addition, ECI does not support thread-reentering. ECI (the API provided by ViaVoice TTS) may have a function limit (possibly due to the evaluation version), so one more thread is used for each Speech object.Keep in mind that SDI is not fully thread-safe.There are some guidelines for you to diminish the number of frustrating problems when you use SDI: So, the system suffers a lot from the intensive use of threading, and thus becoming very instable.

It may sound unnatural, but it really works.īecause sound can't be rendered in a flash, lots of threads and synchronization objects are used in SDI, even the simplistic " Sleep(XXXX)" delay. You can experience two "persons" presenting different news to you at the same time. If you are Chinese or you can speak Chinese, you can turn to NewsEverywhere for a complete online news-reader, including its source code.If you want to learn how to use SDI in a minute, please refer to the sample program.You can check if everything is OK by running the sample program.

This is so-called " cocktail party effect". Academically, this kind of positioning can help the user to pick out desired information out of two concurrently "displaying" sounds. Speech is for positioning synthesized speech in 3D world, combining ViaVoice TTS and A3D together.

At present, the SDI implements two Sound objects: Speech and Earcon. SDI (Sound Device Interface) is designed for Auditory Display, or AUI (Audio User Interface), which has proved to be good complement to GUI (Graphic User Interface) academically. MIDI is owned by MMA (MIDI Manufacturers Association). DirectX is registered trademark of Microsoft Corporation. ViaVoice TTS is registered trademark of IBM. SDI is based on the following products: A3D, ViaVoice TTS, DirectX, MIDI, A3D is owned by Creative Technology Ltd.
