The Pinker-Sato phonology module is a chip-sized component of Starfleet's universal translator. It can be modified with new information on languages.

In 2376, John Candlewood, Cassini and T'rb replicated a Pinker-Sato phonology module that included linguistic comparisons from the USS Defiant's main computer on latest Gamma Quadrant languages. The modified module allowed the crew to communicate with the D'Naali Ryek'ekbalabiozan'voslu when the universal translator began to work. (DS9 novel: Cathedral)

The Pinker-Sato phonology module is likely named for real-life linguist Steven Pinker and ENT's Hoshi Sato.
