<h1>Unconditional Speech Synthesis as Sleeping Aid</h1>
<p>This blog post provides some additional results for our Semester Project on Machine Learning. See <a href="Machine_Learning_Semester_Project.pdf" style="color: rgb(214, 71, 14);">this report</a> for further details.</p>
<h2>Temporal Voice Classification</h2>
<p>We first present the results of some of our temporal voice recognition classifiers. Below, one finds four videos of a small fragment from `Maarten van Rossem - De Podcast'. In these videos, we visualize the output of our classifiers with colors. We use <span style="color:blue">blue</span> to show that the model thinks Maarten van Rossem is talking, <span style="color:red">red</span> for Tom Jessen, and <span style="color:green">green</span> for `Neither'.</p>
<p>The fragment we selected gives our models a challenge, as it contains an active discussion between Maarten van Rossem and Tom Jessen. In addition, the intro tune is still playing slightly in the background.</p>

<h2>Unconditional Speech Synthesis</h2>
<p>Now we present results for speech synthesis. First, some of our final results. Below we show 3 generated fragments of 5 minutes each.</p>

<p>Underneath we show the results of different versions of our model. Version, here, means the number of epochs the model was trained on. We present 3 clips per version. The first of these corresponds to a random seed of 1996. The second 1997, and the third 1998. You will be able to hear similarities between different versions for the same seed. We find that around epoch 110 we get the most desirable results. Epoch 80 was rated the highest in our blind rating procedure described in the report.</p>
