• [hal-04837553] Overt speech decoding from cortical activity: a comparison of different linear methods
  13 décembre 2024
  Introduction Speech BCIs aim at reconstructing speech in real time from ongoing cortical activity. Ideal BCIs would need to reconstruct speech audio signal frame by frame on a millisecond-timescale. Such approaches require fast computation. In this respect, linear decoder are […]
• [hal-04834529] Hardware-Limited Time Constant Estimation Using a Weighted Linear Regression
  12 décembre 2024
  Accurately determining the time constant of a circuit enables IoT nodes to easily read out resistive or capacitive sensors. However, power and cost constraints lead to hardware limitations that complicate such measurements, including ADC noise, sampling clock jitter, poor voltage […]
• [lirmm-04834020] A Modified Cramér-Rao Bound for Discrete-Time Markovian Dynamic Systems
  12 décembre 2024
  It is well-known that the Modified Cramér-Rao Bound (MCRB) holds particular value in nonstandard deterministic estimation scenarios. Specifically, it proves invaluable when, in addition to estimating deterministic parameters, one needs to determine the probability density function (p.d.f) of the data […]
• [hal-03886240] Investigating the role of harmonic cancellation in speech-on-speech masking
  11 décembre 2024
  This study investigated the role of harmonic cancellation in the intelligibility of speech in “cocktail party” situations. While there is evidence that harmonic cancellation plays a role in the segregation of simple harmonic sounds based on fundamental frequency (F0), its […]

• [tel-04793473] Cracking the code of crying babies: how adults learn to understand the baby's pain
  20 novembre 2024
  Babies crying is an essential signal to elicit care, conveying both information on the baby’s identity and current physiological state (discomfort, hunger or pain). The aim of my thesis is to investigate how adults perceive information contained in babies cries, […]
• [tel-04757483] Design of a MEMS microphone based on a new device architecture
  29 octobre 2024
  In recent years, MEMS (micro-electromechanical system) microphones have become a key component in a wide range of consumer electronic devices. The need to improve upon existing applications, such as voice pickup for phone calls, as well as the development of […]

  28 août 2024
  […]
• [tel-04634215] Deep modeling based on voice attributes for explainable speaker recognition : application in the forensic domain
  3 juillet 2024
  Automatic speaker recognition (ASpR) has been integrated into critical applications, ranging from customised assistant services to security systems and forensic investigations. It aims to automatically determine whether two voice samples originate from the same speaker. These systems primarily rely on […]
