Decoding
|
|
========
|
|
|
|
After :ref:`dummies_tutorial_training`, we can start decoding.
|
|
|
|
The command to start the decoding is quite simple:
|
|
|
|
.. code-block:: bash
|
|
|
|
cd /tmp/icefall
|
|
export PYTHONPATH=/tmp/icefall:$PYTHONPATH
|
|
cd egs/yesno/ASR
|
|
|
|
# We use CPU for decoding by setting the following environment variable
|
|
export CUDA_VISIBLE_DEVICES=""
|
|
|
|
./tdnn/decode.py
|
|
|
|
The output logs are given below:
|
|
|
|
.. literalinclude:: ./code/decoding-yesno.txt
|
|
|
|
For the more curious
|
|
--------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
./tdnn/decode.py --help
|
|
|
|
will print the usage information about ``./tdnn/decode.py``. For instance, you
|
|
can specify:
|
|
|
|
- ``--epoch`` to use which checkpoint for decoding
|
|
- ``--avg`` to select how many checkpoints to use for model averaging
|
|
|
|
You usually try different combinations of ``--epoch`` and ``--avg`` and select
|
|
one that leads to the lowest WER (`Word Error Rate <https://en.wikipedia.org/wiki/Word_error_rate>`_).
