Open Source Speech Software

WaveSurfer is an open source tool for sound visualization and manipulation. Typical applications are speech/sound analysis and sound annotation/transcription. WaveSurfer may be extended by plug-ins as well as embedded in other applications.

SPTK is a suite of speech signal processing tools for UNIX environments, e.g., LPC analysis, PARCOR analysis, LSP analysis, PARCOR synthesis filter, LSP synthesis filter, vector quantization techniques, and other extended versions of them.

Ce programme est une démonstration de la reconnaissance vocale de windows 7 en Français N.B il est très important de faire l'apprentissage de votre voix pour avoir de bons résultats. Ce programme reconnait votre voix puis transmet à un logiciel de synthèse vocale l'ordinateur répète ce que vous dites. voir la vidéo http://youtu.be/_bGJxT1ulLY This program is a demonstration of the speech recognition in windows 7 in French. Note it is very important to learn your voice to have good results. This program recognizes your voice and then passes to a speech software the computer repeats what you say. see the video http://youtu.be/T-wfppjhuTg

eXtace is a 3D audio visualization tool (or eye candy depending on how you look at it). eXtace requires ESD (Esound) for its sound input source. It performs a FFT (fast fourier transform) on audio and displays it via various graphical modes.

A collection of scripts and programs to automatically annotate video/audio for subtitles. Basically relies on a MARSYAS (Music Analysis, Retrieval and Synthesis for Audio Signals) plug-in for detecting human voice in polyphonic recordings.

Audacity Policial (aka Audacity Police) is an extension of Audacity sound editor that was created to help police and justice investigations based on phone call and environmental recordings, supporting audio analysis and transcription.

This is a simple DSP simulator for educational purposes: developed as a course supplement of CIT-4617 (Digital Signal Processing) at Islamic University of Technology (IUT). Written in C++.

The purpose of this project is to provide a biometric security solution by using voice print, fingerprint and/or facial recognition along with a password and/or smart card support using AES to protect data. Please read forums for if interested.

Lisn uses the JNI to interface with various media players(winamp/itunes) using either the COM interface or HWND calls. Allows intuitive interaction with the media players as well as a quasi heuristic algorithm for volume control(under development)

Find the pitch of a power spectrum (signal) as per the afferent/efferent neural crossover. This occurs between the Lateral olivocochlear efferents and the inner hair cell afferents.

MARF is a general cross-platform framework with a collection of algorithms for audio (voice, speech, and sound) and natural language text analysis and recognition along with sample applications (identification, NLP, etc.) of its use, implemented in Java.

A Simple Nepali Voice Synthesis Project

SAA (SSPLab Audio Analyzer) It will be able to separate sources, recognize speech and analyze the auditory scene. It can also synthesize spatialised sounds from mono recording, edit, analyze via spectrogram, filter and re-sample signals.

This is a fast C implementation of Arturo Camacho's SWIPE' pitch extraction algorithm. See the project homepage for more about the advantages of the SWIPE' algorithm. swipe-1.0.tar.gz contains the current source, which should compile quite neatly.

SetFon focus is an interface web based for Praat resources (www.praat.org) wich focus speech sound annalysis; it is a gerent program for acoustic analysis PHP/Mysql based. Developed with the framework SIMP.

SimpleSpeech is a research about developing automatic speech recognition (ASR) system that using Hidden Markov Models (HMM) method as the core engine. This research is purposed for students or ASR beginners that being interested in ASR.

'Speak Up' is a TEXT TO SPEECH software.That's not all it has speech recognition and much more.Try it for yourself and send us a feedback on our guestbook. 'Speak Up' 2,0 is packed with new features and upgrades.Check it out for yourself.

Speech Made Visible is an experiment in showing some of the qualities of speech in printed text. Analyze a recording for attributes like pitch, intensity (loudness), and speed; then style the words in a transcript to suggest those characteristics.

ViGiL is supposed to be a platform-independent tool for singing students. In it's final version it should be able to analyze a voice recording (read from audio file or microphone) and compare it to a given score according to melody, rhythm and dynamics.

1.) Investigation with cosine transform, and anti transform algorithm, with some voice recognition code. 2.) Translator: Croatian, English. 3.) 2D to 3D picture algorithm (principle) and new 2Dto3D video conversion code with AviSynth video scripting

Idi is a voice recognition program intended to help people with physical disabilities to use a keyboard by dictating. It can also be used as a way to remote control your computer or as a nice way to type in your bath.

SciSpeech is a speech analysis,synthesis,recogniton toolbox.

The open source, multimodal interactive "Sensitive Artificial Listener" dialogue system created by the EU project SEMAINE.

Yet Another Audio Feature Extractor is a toolbox for audio analysis. Easy to use and efficient at extracting a large number of audio features simultaneously. WAV and MP3 files supported, or embedding in C++, Python or Matlab applications.
