Applying Large-Scale Weakly Supervised Automatic Speech Recognition to Air Traffic Control

The application of automatic speech recognition in the air traffic control domain has been researched extensively. However, its primary application remains in the training and simulation of air traffic controllers. This is due to the insufficient performance of automatic speech recognition in specific environments, such as air traffic control,...

Automatic Speech Recognition for Air Traffic Control Using Open Data

Air Traffic Control (ATC) is tasked with ensuring safe separation between aircraft in a given Controlled Traffic Region (CTR). To achieve this an Air Traffic Controller (ATCo) verbally gives clearances using over the air communication. These clearances are kept track of by the ATCo using so-called ‘flight-strips’, which in modern systems are...

Evaluating the Use of Pitch Shifting to Improve Automatic Speech Recognition Performance on Southern Dutch Accents

Building Automatic Speech Recognizers (ASRs) has been a challenge in languages with insufficiently sized corpora or data sets. A further large issue in language corpora is biases against regionally accented speech and other speaker attributes. There are some techniques to improve ASR performance and reduce biases in these corpora, known as data...

Improving ASR performance on Jasmin Flemish Dutch data by performing frequency perturbation

ASR (automatic speech recognition) systems are used widely in our current day and age. However, for a technology that is used so much in our daily life it contains a lot of bias. This means that not all people can use it equally, people with a different gender, age and dialect will all see different results. The goal of this paper is to reduce...

Evaluating the Use of Frequency Masking on a Hybrid Automatic Speech Recognizer for Transitional Dutch Accent of JASMIN-CGN Corpus

There are many experiments conducted with Automatic Speech Recognition (ASR) systems, but many either focus on specific speaker categories or on a language in general. Therefore, bias could occur in such ASR systems towards different genders, age groups, or dialects. But, to analyze and reduce bias, the models require significant amounts of data...

Improving Automatic Speech Recognition For Dysarthric Speech

Phon Times: Improving Dutch phoneme recognition

In this research, Dutch phoneme recognition (PR) is researched and improved. The last research on Dutch PR dates back to 1995. This research presents Dutch PR in modern daylight by researching state-of-the-art techniques found in research on other languages and implementing them on Dutch PR. The goal of this research is to find the current best...

Evaluating an ASR Pipeline for a Social Robot

There has been a big increase in the use of social robots, such as Pepper, which use verbal communication as the main method of interacting with a human. Verbal communication with a robot is performed using Automatic Speech Recognition (ASR) to recognize words from an audio stream containing speech.<br/>These social robots are being more...

Influence of ASR Degradation on Structural Behavior of Concrete Structures

A lot of concrete structuressufferingfrom ASR show a decrease in material properties. However, it is not clear what might be the influence of ASR on structural behavior. Influence of restraint is often ignored in material property measurement, while reinforcement is present as a restraint of ASR expansion in most structures.Thisresults in so...

Finite Element Modelling of ASR Affected Reinforced Concrete Beams Based on Realistic Pre‐damage

A new type of finite element model, called the double mesh model is proposed in this thesis. With the level of free expansion as the input, the model is able to simulate the restrained ASR expansion by taking into account the effects of physical restraints. The retrained ASR expansion in reinforced concrete cubes and beams are simulated....

Aquifer Storage & Recovery (ASR) system improvement in northern Ghana

The northern Ghana climatological conditions are favourable for agricultural production. The annual average precipitation of 800-1250 mm/y is theoretically sufficient for farmers to be year-round self-sufficient. However, the majority of precipitation falls in a 4-month wet season spanning from late May to October. As a consequence, the region...

bottle | brick: waste glass aggregate replacement in bricks for Zanzibar

This graduation project was initiated by the bottle-up foundation a, small scale company established on Zanzibar, East Africa. bottle-up was founded to tackle the waste glass problem on the island by repurposing and recycling. Through a collaboration with waste collection company Zanrec a monthly volume of 17 tons (15500 kg) of glass is brought...

Subsurface Freshwater Storage & Recovery In Artificial Islands: Case Study of Pluit City Land Reclamation Jakarta, Indonesia

This research seeks to discover the possibilities of Artificial Storage and Recovery (ASR) in an artificial urban island in Jakarta, to increase water security and provide a sustainable water supply.
