Formant plot wavesurfer4/29/2023 ![]() In this paper, we propose a new method for the accurate estimation and tracking of formants in speech signals using time-varying quasi-closed-phase (TVQCP) analysis. Speech-labeled frames, compared to three competitive baselines That our proposed model was easy to converge and achievedĪn overall mean absolute percent error (MAPE) of 8.2% on The problem of gradient disappearance by selectively forgetting ![]() Third, we also adopted a gating mechanism to alleviate Information from all the previous layers through dense connection. Second, each hidden layer reused the output First, we turned off the “causal” mode ofĭilated convolution, making the dilated convolution see the future ![]() The conventional implementation, we modified the architectureįrom three aspects. In this paper, we explored the use of Temporal Convolutional On temporal tasks such as speech synthesis and machine translation. Recent studies showed that genericĬonvolutional architectures can outperform recurrent networks Traditionally, formants are estimated using Results suggest that our proposed model better represents the signal over various domains and leads to better formant frequency tracking and estimation.įormant tracking is one of the most fundamental problems in An advantage of our model is that it is based on heatmaps that generate a probability distribution over formant predictions. Then, multiple decoders further process this representation, each responsible for predicting a different formant while considering the lower formant predictions. Our proposed model is composed of a shared encoder that gets as input a spectrogram and outputs a domain-invariant representation. The contribution of this paper is to propose a new network architecture that performs well on a variety of different speaker and speech domains. However, when presented with a speech from a different domain than that in which they have been trained on, these methods exhibit a decline in performance, limiting their usage as generic tools. Recent work has been shown that those frequencies can accurately be estimated using deep learning techniques. Formants are the spectral maxima that result from acoustic resonances of the human vocal tract, and their accurate estimation is among the most fundamental speech processing problems.
