I have a BSc degree in Computer Engineering (2016) and a MSc degree in Computer Science (2017) conferred by Federal University of Pará (UFPA), Brazil. I’ve also spent one year (2014) as exchange student at the Óbuda University (OE) in Budapest, Hungary. Currently, I am a PhD student in Computer Science at UFPA, in Brazil. Some of my professional experiences include speech recognition for desktop, mobile and embedded platforms; as well as in developing alternative control interfaces for people with disabilities.

What am I (supposed to be) good at?
CMU Sphinx, Kaldi, HTK, and Julius for Brazilian Portuguese
Raspberry Pi, Beagleboard, C.H.I.P., Arduino, etc.
Software- and hardware-based solutions for people with visual, hearing and upper-limb motor disabilities
Routing and wavelength assignment (RWA) simulation in WDM-optical networks
Arch, XMonad, Vim, Git, Python, C, LaTeX, etc.
A universal remote control system in C++ for people with upper-limb motor disabilities, so they could control a TV via alternative methods.
Development of speech (English) modules for controlling Teki: a personal home assistant, Turtlebot-based robot
Development of resources and applications for spech recognition in Brazilian Portuguese:
I decided to post some comments about some excellent online courses related to computing and engineering that I’ve started to take during Covid-19 self-quarantine. Literally all of them are available for free on YouTube.
A system where user’s head gestures are translated into remote commands to electronic devices
A remote control system that translates the user’s spoken words into commands to electronic devices
Estimating the input parameter of Klatt88 formant-based speech synthesizer with long short-term memory neural nets (LSTM).
The first attempt to create scripts and baseline acoustic models for Brazilian Portuguese using Kaldi tools.
An open-source, low cost universal remote control system that translates user’s head poses into commands to electronic devices. In addition, a proximity sensor circuit was combined to radio-frequency modules in order to act as a wireless switch.
A genetic algorithm that aims at solving the RWA problem, which consists of choosing the most suitable lightpath (i.e., a combination of a route and a wavelength channel) between a source-destination pair of nodes in all-optical networks.
This paper describes a cloud speech recognition service in Brazilian Portuguese based on Julius decoder running in server mode. The client side was built on the Android 2.2 platform.
