Conditions controlling tone, pitch, and cadence of voice
This condition classifies as one that most likely does not need any active accommodations. If speech is intelligible then it will not impact gameplay regardless of the tone, pitch, or cadence in which it is delivered.
However, if it does impact communication, allow for additional time during turns. The most important point is to communicate with other players, that the variations in the player's voice may not be indicative of the emotion the player feels. Players that have conditions that impact tone, pitch, and cadence should not be “encouraged” to change their tone to match an expected emotional response.
