A collection of abstraction layers and support functions that form the
natural language processing foundation of the Zamia AI project:

- `phonetics`: translation functions between various phonetic
alphabets (IPA, X-SAMPA, X-ARPABET, …)

- `tts`: abstraction layer towards using eSpeak NG, MaryTTS, SVOX Pico
TTS or a remote TTS server and sequitur g2p

- `asr`: abstraction layer towards using kaldi-asr and pocketsphinx,
models can be found here: <http://goofy.zamia.org/voxforge/>

- `sequiturclient`: g2p using sequitur

- `pulseplayer`: audio playback through pulseaudio

- `pulserecorder`: audio recording through pulseaudio

- `tokenizer`: english and german word tokenizer aimed at spoken
language applications

- `threadpool`: simple thread pool implementation

- `vad`: Voice Activity Detection finite state machine based on webrtc
VAD

I plan to add modules as I need them in the Zamia AI projects. Some
modules like `phonetics` and `tokenizer` have some overlap with larger
projects like NLTK or spaCy - my modules tend to be more hands-on and
simple minded than these and therefore are in no way meant to replace
them.

Requirements
------------

**Note**: probably incomplete.

- for ASR one or more of:

- kaldi-asr 5.1, py-kaldi-asr

- pocketsphinx

- sequitur

- pulseaudio

- webrtc
