=== Write a Dhvani Interface for Speech Dispatcher === | |||
The goal of [http://www.freebsoft.org/speechd Speech Dispatcher] project is to provide a high-level device independent layer for speech synthesis through a simple, stable and well documented interface. Since SD is more discussed to act as a unified TTS layer for both gnome and KDE, We can try to write a Interface for that | |||

===Speech recognition system for Malayalam=== | ===Speech recognition system for Malayalam=== | ||
The aim is to develop a speech recognition system for Malayalam using the concepts of memory prediction framework. Memory prediction framework put forward by Jeff Hawkins in his book 'On Intelligence'(2004) is a theory of brain function, based on the hierarchical organization of human neocortex.It explains how the hierarchical structure enables brain to match sensory inputs to the stored memory patterns for predicting the future input sequences. According to this model, neocortex has a layered structure with different layers storing constructs of varying complexity, with sensory inputs coming to the lowest layer. For example in case of vision, the lower layer receives retinal signals and layers up the hierarchy associates themselves with meaningful constructs like lines, two dimensional figures, and furthur up specific objects like faces etc. In speech the layers store different speech constructs from phonemes and syllables to phrases and sentences. The human speech perception and recognition can be understood using this hierarchical organization. | |||
If we mimic the way in which human brain recognizes speech, the resulting system will be more robust than the existing systems. The proposed system is trained with a carefully compiled database and different speech constructs are stored in different layers.When a speech segment to be recognized is given, a series of predictions start and signals will be passed upwards and downwards the layers, until the most probable speech construct is arrived at. For example if the most probable candidate for first word is 'how', predictions start as to what succeeding words can be. This continues until the last word is arrived at and the phrase giving maximum probability will chosen among these predictions. | |||

===Creating a new family of Equal Height Fonts (EHF)for Malayalam language=== | |||
To design and create a new family of Equal Height Fonts for the traditional Malayalam | |||
script. Following Roman typology, serif and sans serif type of font variations are available in | |||
Malayalam. Equal Width Fonts, such as Courier, available in Roman typography are | |||
impossible for Malayalam characters and this is unnecessary. The proposed Equal Height | |||
Fonts is a new concept in the history of font making to surmount the typographical | |||
challenge of vertically stacked conjuncts. | |||
