inputMinCharacters

This is the minimum number of characters before a chunk is created. The chunks that are sent to the voice provider for the voice generation as the model tokens are streaming in. Defaults to 30.
Increasing this value might add latency as it waits for the model to output a full chunk before sending it to the voice provider. On the other hand, increasing might be a good idea if you want to give voice provider bigger chunks, so it can pronounce them better.
Decreasing this value might decrease latency but might also decrease quality if the voice provider struggles to pronounce the text correctly.
