Time - Domain Two - Dimensional Pitch Detection
THE development of a pitch-detection algorithm faces two basic problems: reliability and computational efficiency. In the research reported here, a pitch-detection algorithm was developed in the context of an audioresponse system with a large vocabulary. The algorithm was designed to be used in a pitch-syuchronous encoding of dictionary words and for prosody experiments. Reliability is the prim...
متن کاملSeismic modeling with minicomputers
The energy crisis has created increased interest in petroleum exploration. Discoveries of major deposits are increasingly rare and difficult to locate. The geophysicist requires more accurate knowledge to assist him in locating deeper and smaller hydrocarbon deposits. While gravity, magnetic, and electrical methods are also used, the predominant exploration tool is the seismic method and provid...
متن کاملRealtime Multiple Pitch Observation using Sparse Non-negative Constraints
In this paper we introduce a new approach for realtime multiple pitch observation of musical instruments. The proposed algorithm is quite different from others in the literature both in its purpose and approach. It is destined not for continuous multiple f0 recognition but rather for projection of the ongoing spectrum to learned pitch templates. The decomposition algorithm on the other hand, do...
متن کاملRational Arithmetic for Minicomputers
A representation for numbers using two computer words is discussed, where the value represented is the ratio of the corresponding integers. This allows for better dynamic range and relative accuracy than single-precision fixed point, yet is less costly than floating point arithmetic. The scheme is easy to implement and particularly well suited for minicomputer applications that call for a great...
متن کاملPitch Detection in Pathological Voices Driven by Three Tailored Classical Pitch Detection Algorithms
Pitch detection is one of the most difficult problems encountered when analyzing speech signals. This paper focuses on detecting the pitch in pathological voices, what is of key importance, for voice pathology diagnosis. In particular, we put special emphasis on diagnosing three common pathologies: roughness, hoarseness and breathiness. The intelligibility and quality of pathological voices are...
