Speech processing tools

Name Description
ANTS Multipass system for transcribing audio data, and in particular radio or TV shows. The audio stream is first split into homogeneous segments of a manageable size, and then each segment is decoded using the most adequate acoustic model with a large vocabulary continuous speech recognition engine (Julius or Sphinx).

Toolbox for audio source separation distributed under the Q Public License.
KAM Framework for source separation, proposed this year by Liutkus et al. as a new and effective approach to source separation.
LASTAS Software for aligning a speech signal with its corresponding orthographic transcription. Using a phonetic lexicon and automatic grapheme-to-phoneme converters, all the potential sequences of phones corresponding to the text are generated. Then, using acoustic models, the tool finds the best phone sequence and provides together the boundaries at the phone level and at the word level.
CoALT Software for comparing the results of several automatic labeling processes through user defined criteria.
Software for Text-To-Speech synthesis (TTS) which relies on a non uniform unit selection algorithm. It performs all steps from text to speech signal output. Moreover, a set of associated tools is available for elaborating a corpus for a TTS system (transcription, alignment…).

Speech visualization tools

Name Description
SNOORI Written in Java and uses signal processing algorithms developed within the WinSnoori software with the double objective of being a platform independent signal visualization and manipulation tool, and also for designing exercises for learning the prosody of a foreign language.

user-friendly software which allows visualizing EMA data acquired by an articulograph. This visualization software has been designed so that it can directly use the data provided by the articulograph to display the articulatory coil trajectories, synchronized with the corresponding acoustic recordings. VisArtico is very useful for the speech science community, and it makes the use of articulatory data more accessible.
Xarticulators Software intended to delineate contours of speech articulators in X-ray images, construct articulatory models and synthesize speech from X-ray films.

Data acquisition

Name Description
JCorpusRecorder Software for the recording of audio corpora. It provides an easy tool to record with a microphone. This software is suitable for recording sentences with information to guide the speaker.
EMA The platform has been improved by acquiring the latest articulograph AG501 funded by the EQUIPEX ORTOLANG project.
MRI Magnetic Resonance Imaging takes an increasing place in the investigation of speech production because it provides a complete geometrical information of the vocal tract.
