Speech tempo (speaking rate) varies both between and within speakers. Previous research suggests several relevant factors and predictors. The present study investigates all these factors combined, both between and within speakers, in a large corpus of spoken Dutch interviews. This is done by means of multi-level modeling of sex, age, and dialect region (all between speakers) and phrase length a...

Interaction with human musicians is a challenging task for robots as it involves online perception and precise synchronization. In this paper, we present a consistent and theoretically sound framework for combining perception and control for accurate musical timing. For the perception, we develop a hierarchical hidden Markov model that combines event detection and tempo tracking. The robot perf...

The song of a male zebra finch is a stereotyped motor sequence whose tempo varies with social context--whether or not the song is directed at a female bird--as well as with the time of day. The neural mechanisms underlying these changes in tempo are unknown. Here we show that brain temperature recorded in freely behaving male finches exhibits a global increase in response to the presentation of...

Skilled musicians are able to shape a given piece of music (by continuously modulating aspects like tempo, loudness, etc.) to communicate high level information such as musical structure and emotion. This activity is commonly referred to as expressive music performance. The present paper presents another step towards the automatic high-level analysis of this elusive phenomenon with AI methods. ...

Christopher Raphael Department of Mathematics and Statistics University of Massachusetts, Amherst [email protected] Abstract A method is presented for the rhythmic parsing problem: Given a sequence of observed musical note onset times, we simultaneously estimate the corresponding notated rhythm and tempo process. A graphical model is developed that represents the evolution of tempo and rhy...

Bicyclic nitroxyl derivatives, such as 2-azaadamantane N-oxyl (AZADO) and 9-azabicyclo[3.3.1]nonane N-oxyl (ABNO), have emerged as highly effective alternatives to TEMPO-based catalysts for selective oxidation reactions (TEMPO = 2,2,6,6-tetramethyl-1-piperidine N-oxyl). Their efficacy is widely attributed to their smaller steric profile; however, electrocatalysis studies described herein show t...

The estimation of the musical tempo of audio signals is of large interest for various applications, e.g. the synchronization of multi-media content to music and music information retrieval systems. This article describes the author’s contribution to the 2 Annual Music Information Retrieval Evaluation Exchange (MIREX 2005) and gives an evaluation and comparison of the recognition performance. Th...

Carboxylic acid groups were introduced onto thermomechanical pulp (TMP) long fiber surfaces by 2,2,6,6,tetramethylpiperidine-1-oxyl radical (TEMPO)-mediated oxidation in the present study. The number of introduced carboxylic groups was closely related to the NaClO dosage, and more flexible fibers with lower curl and kink index were generated. Lignin was dissolved during the TEMPO-mediated oxida...

This paper presents a method for the extraction of music meter and tempo from raw polyphonic audio recordings, assuming that music meter remains constant throughout the recoding. Although this assumption can be restrictive for certain musical genres, it is acceptable for a large corpus of folklore eastern music styles, including Greek traditional dance music. Our approach is based on the selfsi...

Rhythmic descriptors are often utilized for semantic music classification, such as genre recognition or tempo detection. Several algorithms dealing with the extraction of rhythmic information from music signals were proposed in literature. Most of them derive a so-called beat histogram by auto-correlating a representation of the temporal envelope of the music signal. To circumvent the problem o...
