Introduction
How to Talk to Machines"
A short 1-2 day workshop introducing speech recognition and speech synthesis techniques for the creation of interactive artwork. We use pre-compiled open-source tools (CMU Sphinx ASR, Festival TTS, Processing, Python) and focus on the demonstrable strengths and unexpected limitations of speech technologies as vehicles for creating meaning.
Saturday Sept 21, 2-6pm Centro Cultural de Borges UNTREF.
Background Reading:
- If Things Can Talk, What Do They Say? If We Can Talk to Things, What Do We Say? Natalie Jeremijenko. 2005-03-05 [1]
- also see the responses by Simon Penny, Lucy Suchmann, and Natalie linked from that page.
- Dialogue with a Monologue: Voice Chips and the Products of Abstract Speech. [2]
Automatic Speech Recognition
What is it?
- pocketsphinx on win32 - http://www.aiaioo.com/cms/index.php?id=28
Installing CMU Sphinx
http://cmusphinx.sourceforge.net/wiki/download/
Language Models
Acoustic models versus language models.
Grammars versus Satistical Language Models.
Available language models. English, Mandarin, French, Spanish, German, Dutch and more: http://sourceforge.net/projects/cmusphinx/files/Acoustic%20and%20Language%20Models/
Using sphinx
- open a terminal. Windows, Run->Cmd.
- change to the pocketsphinx directory.
cd Desktop\untref_speech\pocketsphinx-0.8-win32\bin\Release
- run the pocketsphinx command to recognize english:
pocketsphinx_continuous.exe -hmm ..\..\model\hmm\en_US\hub4wsj_sc_8k -dict ..\..\model\lm\en_US\cmu07a.dic -lm ..\..\model\lm\en_US\hub4.5000.DMP
- recognize spanish:
pocketsphinx_continuous.exe -hmm ..\..\model\hmm\es_MX\hub4_spanish_itesm.cd_cont_2500 -dict ..\..\model\lm\es_MX\h4.dict -lm ..\..\model\lm\es_MX\H4.arpa.Z.DMP- this should transcribe live from the microphone.
Training your own Models
grammer is trivial.
slm, can use online tools. or try the sphinxtrain packages.
