Anvil, M. Kipp, University of Applied Sciences, Augsburg


“ANVIL is a free video annotation tool, developed by Michael Kipp. It offers multi-layered annotation based on a user-defined coding scheme. During coding the user can see color-coded elements on multiple tracks in time-alignment. Some special features are cross-level links, non-temporal objects, timepoint tracks, coding agreement analysis, 3D viewing of motion capture data and a project tool for managing whole corpora of annotation files. Originally developed for gesture research in 2000, ANVIL is now being used in many research areas including human-computer interaction, linguistics, ethology, anthropology, psychotherapy, embodied agents, computer animation and oceanography.

ANVIL can import data from phonetic tools like PRAAT which allow precise and comfortable speech transcription (see my video tutorial). Anvil can display waveform and pitch contour. Anvil's data files are XML-based. Exported tables can be used for analysis in statistical toolkits like SPSS or Statistica. The coming version will also be able to import ELAN files. ANVIL is written in Java and runs on Windows, Macintosh and Unix platforms.”



Audiamus, N. Thieberger, School of Language and Linguistics, University of Melbourne


“A tool for building corpora of linked transcripts and digitised media.

Audiamus instantiates the links to digitised media. It requires no segmentation of the sound/video file. Currently there is no limit to the size of the media file or the number of transcripts. Each ’card’ of the current model represents a single transcript (typically a complete side of a cassette). Time-aligned transcripts, as produced for example by SoundIndex or Transcriber are the input for Audiamus.

The transcripts in Audiamus are plain text and can be edited, as can the timecodes. Thus the data in Audiamus is the master copy of the transcript that is improved incrementally with use. To avoid the problem of data being locked up in proprietary formats there is a mass export function that dumps all linked text and timecodes to plain text files, or to whatever format the user selects.”

MelAn, J. M. Garrido, Departamento de Lengua Española y Lingüística General, Universidad Nacional de Educación a Distancia


“MelAn is a tool for the automatic stylisation, annotation and modelling of F0 contours. It is made of a set of Praat and R scripts that perform the tasks of F0 stylisation, labelling and modelling. They can be run on Windows, Mac OS X or Linux. It has been conceived for the automatic processing and analysis of large corpora.

The tool applies automatically the framework and methodology for the analysis of F0 contours proposed in Garrido (1996, 2001). This procedure is intended to obtain a symbolic representation of F0 contours which captures their perceptually relevant features, in the sense that it should be possible to build a ‘synthetic’ contour from the symbolic representation almost identical to the original contour from a perceptual point of view.

MelAn is available for public download.”

Speech analysis tools: Praat


Prosogram, P. Mertens, Department of Linguistics, KU Leuven


“Prosogram is a tool for the analysis and transcription of pitch variations in speech. Its stylization simulates the auditory perception of pitch by the listener. A key element in tonal perception is the segmentation of speech into syllable-sized elements, resulting from changes in the spectrum (sound timbre) and intensity. The tool also provides measurements of prosodic features for individual syllables (such as duration, pitch, pitch movement direction and size), as well as prosodic properties of longer stretches of speech (such as speech rate, proportion of silent pauses, pitch range, and pitch trajectory). The tool can easily interact with other software tools. It is used as the first step in automatic phonological transcription of intonation, the detection of sentence stress and intonation boundaries.

Processing steps:

The system is implemented as a Praat script.”


SegProso, J. M. Garrido, Departamento de Lengua Española y Lingüística General, Universidad Nacional de Educación a Distancia
