aeneas is a Python/C library and a set of tools to automagically synchronize audio and text (aka forced alignment). aeneas automatically generates a synchronization map between a list of text fragments and an audio file containing the narration of the text. In computer science this task is known as (automatically computing a) forced alignment.
Features
- aeneas has been developed and tested on Debian 64bit, with Python 2.7 and Python 3.5, which are the only supported platforms at the moment
- Documentation available
- All-in-one installers are available for Mac OS X and Windows
- Input text files in parsed, plain, subtitles, or unparsed (XML) format
- Multilevel input text files in mplain and munparsed (XML) format
- Text extraction from XML (e.g., XHTML) files using id and class attributes
- Arbitrary text fragment granularity (single word, subphrase, phrase, paragraph, etc.)
- Input audio file formats: all those readable by ffmpeg
- MFCC and DTW computed via Python C extensions to reduce the processing time
- Robust against misspelled/mispronounced words, local rearrangements of words, background noise/sporadic spikes
- Adjustable splitting times, including a max character/second constraint for CC applications
