Audacity vamp plugin for deep speech

I've created a VAMP plugin suitable for use with Audacity on Linux to
run Deep Speech on a selected stretch of audio.

This can be used as a friendly frontend to Deep Speech and makes it easy
to preview Deep Speech results on processed audio.

It requires the VAMP SDK to be installed into /usr/include/vamp-sdk
and it requires a recent version of GCC supporting C++14.

Looks awesome! I have a question though, it seems like you rely on the
Python bindings within your C++ codebase? If so, is there any reason not
to use the C++ lib?

Indeed, the plugin relies on a Python script (via fork/exec in C++) that
uses the Python bindings. When I started working on the plugin I didn't
know about the C++ library.

Now that I've tried to get the C++ library working I see I need to setup
my computer to build Tensorflow and Deep Speech; that's not nearly as
convenient as simply running pip install to fetch and install a
prebuilt wheel.

After downloading and extracting the pre-built native_client
binaries,
I get an error when running deepspeech because I don't have
libsox.so.2 installed (only libsox.so.3):

$ ./deepspeech --help
./deepspeech: error while loading shared libraries: libsox.so.2: cannot open shared object file: No such file or directory
$ pacman -Qo /usr/lib/libsox.so.*
/usr/lib/libsox.so.3 is owned by sox 14.4.2-2
/usr/lib/libsox.so.3.0.0 is owned by sox 14.4.2-2

Do you know which Linux distro the pre-built binaries are built for? It
doesn't seem to be specified in the README for native_client.

We're building that on some ubuntu 14.04 that's why we have the
dependency against sox 2. Someone on github issues contributed an AUR
package that does links against sox3 :-). Technically you don't need to
rebuild everything, only the deepspeech binary links against sox but
libdeepspeech does not requires sox

Here's the ArchLinux package:

Thanks for the hint that
libdeepspeech itself doesn't need sox! I've updated my plugin to use
the C++ library instead. That made the implementation about 200 lines
shorter
