exposure to auditory Feedback Delay while speaking induces perceptual habituation but does not mitigate the disruptive effect of Delay on speech auditory motor learning
Neuroscience, 2020Co-Authors: Douglas M Shiller, Takashi Mitsuya, Ludo MaxAbstract:Abstract Perceiving the sensory consequences of our actions with a Delay alters the interpretation of these afferent signals and impacts motor learning. For reaching movements, Delayed visual Feedback of hand position reduces the rate and extent of visuomotor adaptation, but substantial adaptation still occurs. Moreover, the detrimental effect of visual Feedback Delay on reach motor learning—selectively affecting its implicit component—can be mitigated by prior habituation to the Delay. Auditory-motor learning for speech has been reported to be more sensitive to Feedback Delay, and it remains unknown whether habituation to auditory Delay reduces its negative impact on learning. We investigated whether 30 min of exposure to auditory Delay during speaking (a) affects the subjective perception of Delay, and (b) mitigates its disruptive effect on speech auditory-motor learning. During a speech adaptation task with real-time perturbation of vowel spectral properties, participants heard this frequency-shifted Feedback with no Delay, 75 ms Delay, or 115 ms Delay. In the Delay groups, 50% of participants had been exposed to the Delay throughout a preceding 30-minute block of speaking whereas the remaining participants completed this block without Delay. Although habituation minimized awareness of the Delay, no improvement in adaptation to the spectral perturbation was observed. Thus, short-term habituation to auditory Feedback Delays is not effective in reducing the negative impact of Delay on speech auditory-motor adaptation. Combined with previous findings, the strong negative effect of Delay and the absence of an influence of Delay awareness suggest the involvement of predominantly implicit learning mechanisms in speech.

modulation of auditory motor learning in response to formant perturbation as a function of Delayed auditory Feedback
Journal of the Acoustical Society of America, 2017Co-Authors: Takashi Mitsuya, Kevin G. Munhall, David W PurcellAbstract:The interaction of language production and perception has been substantiated by empirical studies where speakers compensate their speech articulation in response to the manipulated sound of their voice heard in real-time as auditory Feedback. A recent study by Max and Maffett [(2015). Neurosci. Lett. 591, 25–29] reported an absence of compensation (i.e., auditory-motor learning) for frequency-shifted formants when auditory Feedback was Delayed by 100 ms. In the present study, the effect of auditory Feedback Delay was studied when only the first formant was manipulated while Delaying auditory Feedback systematically. In experiment 1, a small yet significant compensation was observed even with 100 ms of auditory Delay unlike the past report. This result suggests that the tolerance of Feedback Delay depends on different types of auditory errors being processed. In experiment 2, it was revealed that the amount of formant compensation had an inverse linear relationship with the amount of auditory Delay. One of...

the effect of block wise Feedback on the throughput Delay trade off in streaming
International Conference on Computer Communications, 2014Co-Authors: Gauri Joshi, Yuval Kochman, Gregory W WornellAbstract:Unlike traditional file transfer where only total Delay matters, streaming applications impose Delay constraints on each packet and require them to be in order. To achieve fast in-order packet decoding, we have to compromise on the throughput. We study this trade-off between throughput and in-order decoding Delay, and in particular how it is affected by the frequency of block-wise Feedback, whereby the source receives full channel state Feedback at periodic intervals. Our analysis shows that for the same throughput, having more frequent Feedback significantly reduces the in-order decoding Delay. For any given block-wise Feedback Delay, we present a spectrum of coding schemes that span different throughput-Delay tradeoffs. One can choose an appropriate coding scheme from these, depending upon the Delaysensitivity and bandwidth limitations of the application.

the effect of block wise Feedback on the throughput Delay trade off in streaming
arXiv: Information Theory, 2014Co-Authors: Gauri Joshi, Yuval Kochman, Gregory W WornellAbstract:Unlike traditional file transfer where only total Delay matters, streaming applications impose Delay constraints on each packet and require them to be in order. To achieve fast in-order packet decoding, we have to compromise on the throughput. We study this trade-off between throughput and in-order decoding Delay, and in particular how it is affected by the frequency of block-wise Feedback to the source. When there is immediate Feedback, we can achieve the optimal throughput and Delay simultaneously. But as the Feedback Delay increases, we have to compromise on at least one of these metrics. We present a spectrum of coding schemes that span different points on the throughput-Delay trade-off. Depending upon the Delay-sensitivity and bandwidth limitations of the application, one can choose an appropriate operating point on this trade-off.

a multi burst transmission strategy for streaming over blockage channels with long Feedback Delay
IEEE Journal on Selected Areas in Communications, 2011Co-Authors: Huan Yao, Yuval Kochman, Gregory W WornellAbstract:We consider streaming over a blockage channel with long Feedback Delay, as arises in, e.g., real-time satellite communication from a comm-on-the-move (COTM) terminal. For this problem, we introduce a definition of Delay that captures the real-time nature of the problem, which we show grows at least as fast as O(log(k)) for memoryless channels, where k corresponds to the number of packets in the transmission. Moreover, a tradeoff exists between this Delay and a natural notion of throughput we introduce to capture the bandwidth requirements of the communication. We develop and analyze an efficient "multi-burst" transmission (MBT) protocol for achieving good Delay-throughput tradeoffs within this framework, which we show to be robust and near-optimal within the class of retransmission protocols with fixed schedules. The MBT protocol can be augmented with coding for additional performance gains. Simulations validate the new protocols, including when peak bandwidth and Delay constraints are imposed.

a retransmission strategy for real time streaming over satellite in blockage with long memory
Military Communications Conference, 2011Co-Authors: Huan Yao, Yuval Kochman, Gregory W WornellAbstract:The channel for a Comm-on-the-move (COTM) terminal in a blockage environment communicating over a satellite can be characterized as a packet erasure channel with long channel memory and long Feedback Delay. The goal of our research is to enable real-time application, such as a two-way voice call, over such a challenging channel. These packets need to be delivered reliably with strict order requirement. While various automatic repeat request (ARQ) techniques are often used for this purpose, they become ineffective when the channel is severely blocked with long memory and long Feedback Delay, and the user desires Delay performance that is only a small amount above the physical limit of the channel while not consuming too much bandwidth.

Energy-Latency Tradeoff in Ultra-Reliable Low-Latency Communication With Retransmissions
IEEE Journal on Selected Areas in Communications, 2018Co-Authors: Apostolos Avranas, Marios Kountouris, Philippe CiblatAbstract:High-fidelity, real-time interactive applications are envisioned with the emergence of the Internet of Things and tactile Internet by means of ultra-reliable low-latency communications (URLLC). Exploiting time diversity for fulfilling the URLLC requirements in an energy efficient manner is a challenging task due to the nontrivial interplay among packet size, retransmission rounds and Delay, and transmit power. In this paper, we study the fundamental energy-latency tradeoff in URLLC systems employing incremental redundancy (IR) hybrid automatic repeat request (HARQ). We cast the average energy minimization problem with a finite blocklength (latency) constraint and Feedback Delay, which is non-convex. We propose a dynamic programming algorithm for energy efficient IR-HARQ optimization in terms of number of retransmissions, blocklength, and power per round. Numerical results show that our IR-HARQ approach could provide around 25% energy saving compared with one-shot transmission (no HARQ).
