+********************
+SpeechBrain
+********************
+
+In this short tutorial, we're going to demonstrate how OrĂon can be integrated to a `SpeechBrain
+`_ speech recognition model.
+The files mentioned in this tutorial are available in the `OrĂon
+`_ repository.
+
+Installation and setup
+======================
+
+Make sure OrĂon is installed (:doc:`/install/core`).
+
+Then install SpeechBrain using ``$ pip install speechbrain``
+
+Adapting the Speechbrain for OrĂon
+==================================
+
+The Adaptation for using OrĂon is quite simple.
+
+1) We first need to import orion.report_objective() into the project.
+
+.. code-block:: python
+
+ from orion.client import report_objective
+
+2) We then need to change the evaluation from the training data to the validation data.
+The evaluation method should look like this. It returns the validation loss.
+
+.. literalinclude:: /../../examples/speechbrain_tutorial/main.py
+ :language: python
+ :lines: 75-80
+
+3) Finally, we call ``report_objective`` at the end to return the final objective value,
+the validation loss, to OrĂon.
+
+.. code-block:: python
+
+ report_objective(valid_stats)
+
+The code is now adapted and ready to be used with OrĂon.
+
+Execution
+=========
+
+We are now going to call the orion hunt function. Notice that we still need to give the train.yaml
+file to speechbrain, since the general configuration is in there. However, we are going to specify
+the hyper-parameters that we want to optimize after that,
+which will automatically overrides the ones set in the train.yaml.
+
+.. code-block:: bash
+
+ orion hunt \
+ --enable-evc -n \
+ python main.py train.yaml \
+ --lr~'loguniform(0.05, 0.2)' \
+ --ctc_weight~'loguniform(0.25, 0.75)' \
+ --label_smoothing~'loguniform(1e-10, 10e-5)' \
+ --coverage_penalty~'loguniform(1.0, 2.0)' \
+ --temperature~'loguniform(1.0, 1.5)' \
+ --temperature_lm~'loguniform(1.0, 1.5)'
+
+Results
+=======
+
+When an experiment reaches its termination criterion, basically ``max-trials``,
+you can see the results using the command
+
+.. code-block:: bash
+
+ $ orion info -n
+
+This outputs the following statistics
+
+.. code-block:: bash
+
+ Stats
+ =====
+ completed: True
+ trials completed: 209
+ best trial:
+ id: 8675cfcfba768243e1ed1ac7825c69b6
+ evaluation: 0.13801406680803444
+ params:
+ /coverage_penalty: 1.396

+"""Recipe for training a sequence-to-sequence ASR system with mini-librispeech.
+The system employs an encoder, a decoder, and an attention mechanism
+between them. Decoding is performed with beam search coupled with a neural
+language model.
+
+To run this recipe, do the following:
+> python train.py train.yaml
+
+With the default hyperparameters, the system employs an LSTM encoder.
+The decoder is based on a standard GRU. Beam search coupled with an RNN language
+model is used on the top of decoder probabilities.
+
+The neural network is trained on both CTC and negative-log likelihood
+targets and sub-word units estimated with Byte Pairwise Encoding (BPE)
+are used as basic recognition tokens. Training is performed on the mini-librispeech
+dataset. Note that this is a tiny dataset used here just to
+provide a working example. To achieve a better performance you have to train with
+larger datasets, such as the full LibriSpeech one. In this case, to allow the
+model to converge, we pre-train it with a bigger one (trained on the full librispeech
+with the seq2seq 1k BPE recipe).
+
+The experiment file is flexible enough to support a large variety of
+different systems. By properly changing the parameter files, you can try
+different encoders, decoders, tokens (e.g, characters instead of BPE).
+
+This recipe assumes that the tokenizer and the LM are already trained.
+To avoid token mismatches, the tokenizer used for the acoustic model is
+the same use for the LM. The recipe downloads the pre-trained tokenizer
+and LM.
+
+If you would like to train a full system from scratch do the following:
+1- Train a tokenizer (see ../Tokenizer)
+2- Train a language model (see ../LM)
+3- Train the speech recognizer (with this code).
