Since the detailed analysis of F0 estimation is quite extensive, this article is supposed to provide a brief overview of the topic that will be useful for the reader’s further investigation. In this article the audio track’s listener is a neural network (instead of a human) another article explains the Yanny/Laurel phenomena from the speech production perspective. The transition can be noticed on one device as well, for example, here. So, when listening to the recordings in the systems with high-quality low-frequency reproduction, you’ll hear Laurel, and in audio systems where low frequencies are poorly reproduced, Yanny.

And in an audio record of poor quality, it can be difficult to estimate F0 because the desired peak at low frequencies almost disappears.īy the way, do you remember Laurel and Yanny auditory illusion? Differences in the words people hear when listening to the same audio record arise because of the differences in perception of F0, which is influenced by many factors: the age of the listener, the degree of how tired the listener is, the quality of the audio system. For example, it can be often confused with harmonics - this can lead to so-called pitch doubling/pitch halving. However, there is a number of difficulties one faces while estimating F0.

In healthcare, detection of the pathological characteristics of the voice (for example, using the acoustic parameters of Jitter and Shimmer): F0 could be used for the detection of signs of Parkinson’s disease Jitter and Shimmer can also be used for Emotion Recognition.

Speaker deterioration, or splitting the speech into phrases.

The variability of the fundamental frequency is quite large, and it can vary greatly not only between people (for lower average male voices the frequency is 70–200 Hz, and for women it can reach 400 Hz), but also for one person, especially in emotional speech. *Note that the split on voiced/unvoiced sounds is not equivalent to the split on vowels and consonants. When pronouncing unvoiced sounds, for example, by whispering or uttering hissing and whistling sounds, the ligaments do not vibrate, which means that this characteristic is not relevant. The fundamental frequency, which is also referred to as F0, is the vibration frequency of the ligaments when pronouncing voiced sounds. To begin with, let’s remember what the fundamental frequency is and in what tasks it may be needed. In this article we will discuss the features of the algorithms for its estimation and compare the existing solutions on audio recordings. However, estimation of the fundamental frequency is not a trivial task, which has its interesting ins and outs.

And the intonation, for example, is associated with expressive characteristics of the voice. The fundamental frequency is directly related to what we call the intonation. The pitch of the voice is one of the main characteristics, but in the field of acoustic technologies the correct name of this parameter is the fundamental frequency. The voice can be characterized by several parameters. It does not store any personal data.In Emotion Recognition, the voice is the second most important source of affective data, after the face.
