13. Sistema de conversão texto-fala para a lingua portuguesa utilizando a abordagem de sintese por regras
This work contains a description of the text-to-speech conversion system for the Portuguese of Brazil developed at the Signal Processing Laboratory of the Electrical and Computer Engineering School of Unicamp. The system receives as input a generic text in Portuguese and produces as output the corresponding speech signal. The text-to-speech conversion proces

14. Unsupervised learning of natural languages
We address the problem, fundamental to linguistics, bioinformatics, and certain other disciplines, of using corpora of raw symbolic sequential data to infer underlying rules that govern their production. Given a corpus of strings (such as text, transcribed speech, chromosome or protein sequence data, sheet music, etc.), our unsupervised algorithm recursively

15. Syntactic sequencing in Hebbian cell assemblies
Hebbian cell assemblies provide a theoretical framework for the modeling of cognitive processes that grounds them in the underlying physiological neural circuits. Recently we have presented an extension of cell assemblies by operational components which allows to model aspects of language, rules, and complex behaviour. In the present work we study the genera

16. Grammatical model of the regulation of gene expression.
Based on a formal proof that justifies the search for generative grammars in the study of gene regulation, a linguistic formalization of an exhaustive data base of Escherichia coli sigma 70 promoters and their regulatory binding sites has been initiated. The grammar presented here generates all the arrays of the collection plus those that are predicted as co

17. Brain signatures of artificial language processing: Evidence challenging the critical period hypothesis
Adult second language learning seems to be more difficult and less efficient than first language acquisition during childhood. By using event-related brain potentials, we show that adults who learned a miniature artificial language display a similar real-time pattern of brain activation when processing this language as native speakers do when processing

18. The evolution of language
The emergence of language was a defining moment in the evolution of modern humans. It was an innovation that changed radically the character of human society. Here, we provide an approach to language evolution based on evolutionary game theory. We explore the ways in which protolanguages can evolve in a nonlinguistic society and how specific signals can
