Deep Learning systems for training and testing disfluency detection and related tasks on speech data.
Deep Learning Driven Incremental Disfluency Detection
Code for Deep Learning driven incremental disfluency detection and related dialogue processing tasks.
The deep disfluency tagger consumes words (and optionally, POS tags and word timings) word-by-word and outputs xml-style tags for each disfluent word, symbolising each part of any repair or edit term detected. The tags are:
<e/> - an edit term word, not necessarily inside a repair structure
<rms id=“N”/> - reparandum start word for repair with ID number N
<rm id=“N”/> - mid-reparandum word for repair N
<i id=“N”/> - interregnum word for repair N
<rps id=“N”/> - repair onset word for repair N (where N is normally the 0-indexed position in the sequence)
<rp id=“N”/> - mid-repair word for repair N
<rpn id=“N”/> - repair end word for substitution or repetition repair N
<rpndel id=“N”/> - repair end word for a delete repair N
Every repair detected or in the gold standard will have at least the
rpndel tags, but the others may not be present.
Some example output on Switchboard utterances is as below, where
<f/> is the default tag for a fluent word:
4617:A:15:h 1 uh UH <e/> 2 i PRP <f/> 3 dont VBPRB <f/> 4 know VB <f/> 4617:A:16:sd 1 the DT <rms id="1"/> 2 the DT <rps id="1"/><rpn id="1"/> 3 things NNS <f/> 4 they PRP <f/> 5 asked VBD <f/> 6 to TO <f/> 7 talk VB <f/> 8 about IN <f/> 9 were VBD <f/> 10 whether IN <rms id="12"/> 11 the DT <rm id="12"/> 12 uh UH <i id="12"/><e/> 13 whether IN <rps id="12"/> 14 the DT <rpn id="12"/> 15 judge NN <f/> 16 should MD <f/> 17 be VB <f/> 18 the DT <f/> 19 one NN <f/> 20 that WDT <f/> 21 does VBZ <f/> 22 the DT <f/> 23 uh UH <e/> 24 sentencing NN <f/>
Set up and basic use
To run the code here you need to have
Python 2.7 installed, and also
pip for installing the dependencies.
You need to run the below from the command line from inside this folder (depending on your user status, you may need to prefix the below with
sudo or use a virtual environment):
pip install -r requirements.txt
If you just want to use the tagger off-the-shelf see the usage in
demo.py or the notebook
Make sure this repository is on your system path if you want to use it in python more generally.
Use with live ASR
If you would like to run a live ASR version using the IBM Watson speech-to-text recognizer, you need to also do the following:
- Install PortAudio - a free, cross-platform, open-source, audio I/O library. Install it first.
- Prepare your credentials from IBM Watson (free trials are available):
- Visit the IBM Watson projects page.
- Choose your project.
- Copy the credentials to
credentials.jsoninto this directory.
The ASR live streaming demo at
asr_demo.py can then be run and you should be able to see the recognized words, timings, POS tags, and disfluency tags appearing in real time as you speak into your microphone.
The code can be used to run the experiments on Recurrent Neural Networks (RNNs) and LSTMs from:
Julian Hough and David Schlangen. Joint, Incremental Disfluency Detection and Utterance Segmentation from Speech. Proceedings of EACL 2017. Valencia, Spain, April 2017.
Please cite the paper if you use this code.
If you are using our pretrained models as in the usage in
demo.py you can simply run
deep_disfluency/experiments/EACL_2017.py, ensuring the boolean variables at the top of the file to:
download_raw_data = False create_disf_corpus = False extract_features = False train_models = False test_models = True
If that level of reproducibility does not satisfy you, you can set all those boolean values to
True (NB: be wary that training the models for each experiment in the script can take 24hrs+ even with a decent GPU).
Once the script has been run, running the Ipython notebook at
deep_disfluency/experiments/analysis/EACL_2017/EACL_2017.ipynb should process the outputs and give similar results to those recorded in the paper.
This basis of these models is the disfluency and dialogue act annotated Switchboard corpus, based on that provided by Christopher Potts's 2011 Computational Pragmatics course ([[at http://compprag.christopherpotts.net/swda.html]]) or at [[https://github.com/cgpotts/swda]]. Here we use Julian Hough's fork which corrects some of the POS-tags and disfluency annotation:
The second basis is the word timings data for switchboard, which is a corrected version with word timing information to the Penn Treebank version of the MS alignments, which can be downloaded at:
Extra: using the Switchboard audio data
If you are satisfied just using lexical/POS/Dialogue Acts and word timing data alone, the above are sufficient, however if you want to use other acoustic data or generate ASR results from scratch, you must have access to the Switchboard corpus audio release. This is available for purchase from:
From the switchboard audio release, copy or move the folder which contains the .sph files (called
swbd1) to within the
deep_disfluency/data/raw_data/ folder. Note this is very large at around 14GB.
Future: Creating your own data
Training data is created through creating dialogue matrices (one per speaker in each dialogue), whereby the format of these for each row in the matrix is as follows, where
, indicates a new column, and
... means there are potentially multiple columns:
word index, pos index, word duration, acoustic features..., lm features..., label
There are methods for creating these in the
