Syllable lattices as a basis for a children's speech reading tracker

Proceedings of Interspeech 2007, Antwerp (Belgium)In this paper we present an algorithm that makes use of information contained in syllable lattices to significantly reduce the classification error rate of a children’s speech reading tracker. The task is to verify whether each word in a reference string was actually spoken. A syllable graph is generated from the reference word string to represent acceptable pronunciation alternatives. A syllable based continuous speech recognizer is used to generate a syllable lattice. The best alignment between the reference graph and the syllable lattice is determined using a dynamic programming algorithm. The speech vectors that are aligned with each syllable are used as features for Support Vector Machine classifiers that accept or reject each syllable in the aligned path. Experimental results over three children’s speech corpora show that this algorithm can substantially reduce the classification error rate over the standard word based tracker and over a simple best-path syllable based tracker

Interpreting parametric-biomimicry design from cad тo bim software: digital modelling based on a sketch of nandi flame

This research represents an application of two digital modelling softwares, first digital modelling software, chosen as representative of Computer-Aided Design – CAD modelling tool was Fusion 360. The representative of Building Information Modelling (BIM) as second digital modelling software was ArchiCAD. The aim of the research was to translate the same parametric-biomimicry design methodology used in CAD process modelling into BIM environment. African species Spathodea campanulata P. Beauv, whose common name in Kenya is Nandi flame, has been selected for the purpose of this digital modelling processes. As one of the most spectacular flowering plants, Nandi flame is indigenous to the tropical dry forests in Kenya. The decorative flower of this species was the basic model, more precisely the botanical sketches of the flower. This sketches were implemented into digital modelling softwares and used for parametric modelling. The results of this processes were represented as urban models or installations (landscape-architectural elements) in open space. This approach of digitally generating conceptual solutions from nature elements has capability to boost the formulation of new creative inventions in the different fields. The unique geometric patterns found in the flower of Spathodea campanulata P. Beauv served as a good example of how we may transform these ideas into actual design installations– using CAD or BIM software tools. This research has been carried out with the aim to find the position of BIM tools in parametric biomimicry design
