+    // This is a speech synthesizer based on the Votrax SC-02
+    // There are 2 sound generators, one for the voice and one for the noise
+    // The voice generator is a saw-tooth wave generator at a frequency determined by the voice frequency register
+    // The noise generator is a pseudo-random noise generator
+
+    // The Votrax has 5 filters that can be applied to the voice generator, controlled by a filter frequency register
+    // The fifth filter takes both the voice and noise generators as input, but other filters only take the voice generator
+    // There is also a final high-pass filter that can be applied to the output of the voice and noise generators
+
+    // There is a phoneme register which controls the phoneme to be spoken (0-63)
+    // There is a duration register which controls the duration of the phoneme (0-3)
+    // There is a rate register which controls the rate of speech (0-15)
+    // There is an inflection register which controls the inflection of the voice (0-15)
+
+    // For each phoneme there are 8 bytes that control the filters and sound generator levels
+    byte[] phonemeData = new byte[64 * 8];
+    // Phoneme chart:
