Analysis

ESPS

  • ESPS - Entropic Signal Processing System, is a package of UNIX-like commands and programming libraries for speech signal processing. As a commercial product of Entropic Research Laboratory, Inc, it became extremely widely used in phonetics and speech technology research laboratories in the 1990's, in view of the wide range of functions it offered, such as get_f0 (for fundamental frequency estimation), formant (for formant frequency measurement), the xwaves graphical user interface, and many other commands and utilities. Following the acquisition of Entropic by Microsoft in 1999, Microsoft and AT&T licensed ESPS to the Centre for Speech Technology at KTH, Sweden, so that a final legacy version of the ESPS source code could continue to be made available to speech researchers. At KTH, code from the ESPS library (such as get_f0) was incorporated by Kåre Sjölander and Jonas Beskow into the Wavesurfer speech analysis tool. This is a very good alternative way to use many ESPS functions if you want a graphical user interface rather than scripting.



Speech Research Tools

Most of the code is in Python, with C/C++ supporting code. Also, contains code releases corresponding to publishe

HTK Speech Recognition Toolkit

  • HTK Speech Recognition Toolkit - a portable toolkit for building and manipulating hidden Markov models. HTK is primarily used for speech recognition research although it has been used for numerous other applications including research into speech synthesis, character recognition and DNA sequencing. HTK is in use at hundreds of sites worldwide.HTK consists of a set of library modules and tools available in C source form. The tools provide sophisticated facilities for speech analysis, HMM training, testing and results analysis. The software supports HMMs using both continuous density mixture Gaussians and discrete distributions and can be used to build complex HMM systems. The HTK release contains extensive documentation and examples.

speechrate

  • speechrate - software for the analysis of speech. Below you will find a script that automatically detects syllable nuclei in order to measure speech rate without the need of a transcription. Peaks in intensity (dB) that are preceded and followed by dips in intensity are considered as potential syllable nuclei. The script subsequently discards peaks that are not voiced. On this page you find an example of how the script works.

WARP-Q

  • https://github.com/wjassim/WARP-Q - code is to run the WARP-Q speech quality metric. WARP-Q (Quality Prediction For Generative Neural Speech Codecs) is an objective, full-reference metric for perceived speech quality. It uses a subsequence dynamic time warping (SDTW) algorithm as a similarity between a reference (original) and a test (degraded) speech signal to produce a raw quality score. It is designed to predict quality scores for speech signals processed by low bit rate speech coders.

Abstract: We present an emotion recognition system for nonverbal vocalizations (NVs) submitted to the ExVo Few-Shot track of the ICML Expressive Vocalizations Competition 2022. The proposed method uses self-supervised learning (SSL) models to extract features from NVs and uses a classifier chain to model the label dependency between emotions. Experimental results demonstrate that the proposed method can significantly improve the performance of this task compared to several baseline methods. Our proposed method obtained a mean concordance correlation coefficient (CCC) of in the validation set and in the test set, while the best baseline method only obtained in the validation set.

Transcribe!

  • Transcribe! - an assistant for people who want to work out a piece of music from a recording, in order to write it out, or play it themselves, or both. It doesn't do the transcribing for you, but it is essentially a specialised player program which is optimised for the purpose of transcription. It has many transcription-specific features not found on conventional music players. It is also used by many people for play-along practice. It can change pitch and speed instantly, and you can store and recall any number of named loops. So you can practice in all keys, and you can speed up as well as slow down. There is some advice about play-along practice in Transcribe!'s help, under the heading "Various Topics". And it is also used for speech transcription. With its support for foot pedals and its superior slowed-down sound quality, it is an excellent choice for this purpose.

Voice control


  • YouTube: "Voice Driven Development: Who needs a keyboard anyway?" by Emily Shea - As a programmer, being unable to use a keyboard can seem like a career-ending limitation. I was facing that reality a year ago due to Repetitive Strain Injury, when every productive day was a step back for my health. In a futile, last-ditch effort at saving my career, I turned to speech recognition. Unexpectedly, not only was I able to return to pain-free productivity, but I found voice-driven development to be enjoyable, efficient, and a source of renewed excitement for programming. Speech recognition isn't exactly known in software development circles as a workable approach to programming, but it's better than you (probably) think! Far from imposing a tedious workflow with a specialized set of commands, speech can enable flexibility and optimizations that are difficult to achieve with a keyboard, and does not get in the way when adapting to new technologies, tools, or languages. This practical, demo-driven talk presents the approach and tools that have allowed me to continue on with my career. I'll present real world experience with speech-related topics like disambiguating homophones on the fly and teaching the voice engine new technical vocabulary. Beyond technical aspects, I will share my experience guiding a team to support this working style, and challenges to adding a microphone into an open office environment. Speech not only removes the compromise between health and career when an injury is present, but can also augment and improve the workflow for a wider audience.

This is command, and it's right on the tip of your tongue! Start with the tutorial, which has a lot of screenshots.


Xvoice

  • Xvoice - enables continuous speech dictation and speech control of most X applications. To convert users' speech into text it uses the IBM ViaVoice speech recognition engine, which is distributed separately (see below).When in dictation mode Xvoice passes this text directly to the currently focused X application. When in command mode, Xvoice matches the speech with predefined, user-modifieable, key sequences or commands. For instance "list" would match "ls -l" when commanding the console, so that when the user says "list" "ls -l" will be sent to the console as if the user had typed it.

unified2021

  • https://github.com/nay0648/unified2021 - A UNIFIED SPEECH ENHANCEMENT FRONT-END FOR ONLINE DEREVERBERATION, ACOUSTIC ECHO CANCELLATION, AND SOURCE SEPARATION. Dereverberation (DR), acoustic echo cancellation (AEC), and blind source separation (BSS) are the three most important submodules in speech enhancement front-end. In traditional systems, the three submodules work independently in a sequential manner, each submodule has its own signal model, objective function, and optimization policy. Although this architecture has high flexibility, the speech enhancement performance is restricted, since each submodule's optimum cannot guarantee the entire system's global optimum. In this paper, a unified signal model is derived to combine DR, AEC, and BSS together, and the online auxiliary-function based independent component/vector analysis (Aux-ICA/IVA) technique is used to solve the problem. The proposed approach has unified objective function and optimization policy, the performance improvement is verified by simulated experiments.
