In augmented reality applications, where room geometries and material properties are not readily available, it is desirable to get a representation of the sound field in a room from a limited set of available room impulse response measurements. In this paper, we propose a novel method for 2D interpolation of room modes from a sparse set of RIR measurements that are non-uniformly sampled within a space. We first obtain the mode parameters of a measured room. We derive a layer- wise recurrence without the assumptions of previous work, and show that it leads to a standard recurrence with modest modifications to reflect use of log-probabilities.

A plurality of the papers, however, concentrate on the core technology of automatic speech recognition ASR , or converting an acoustic speech signal into text:. Two of the papers address language or code switching , a more complicated version of ASR in which the speech recognizer must also determine which of several possible languages is being spoken:. Such paralinguistic signals can be useful for a voice agent trying to determine how to interpret the raw text. Several papers address other extensions of ASR , such as speaker diarization , or tracking which of several speakers issues each utterance; inverse text normalization , or converting the raw ASR output into a format useful to downstream applications; and acoustic event classification , or recognizing sounds other than human voices:. Speech enhancement , or removing noise and echo from the speech signal, has been a prominent topic at ICASSP since the conference began in All of the preceding research topics have implications for voice services like Alexa, but Amazon has a range of other products and services that rely on audio-signal processing. Another paper investigates the topic of singing voice separation , or separating vocal tracks from instrumental tracks in song recordings:. One paper investigates federated learning , a distributed-learning technique in which multiple servers, each with a different, local store of training data, collectively build a machine learning model without exchanging data. The other presents a new loss function for training classification models on synthetic data created by transforming real data — for instance, training a sound classification model with samples that have noise added to them artificially.

While it is possible to simulate how sound waves physically propagate, scatter and diffract in an environment, this requires significant computational resources. In many cases, it is possible, and indeed desirable, to simplify the simulation and rendering of room acoustics by leveraging limitations of human auditory perception. This tutorial will provide an overview of the available classes of room acoustics models with a focus on models with low computational requirements that are particularly suitable for XR applications. Description: Images, videos, and audios that are created or manipulated by AI algorithms, in particular, deep neural networks DNNs , are a recent twist to the disconcerting problem of online disinformation. The AI-based fake contents, hereafter referred to as the DeepFakes, range from realistic images generated or edited with the generative adversarial network GAN models, to face-swapping videos created with auto-encoder network models the origin of the namesake , and indistinguishable human voices created with recursive neural network models.
