Microsoft and its subsidiary Nuance Communications have reached an agreement in principle to end a copyright suit brought by Cerence over text-to-speech software, according to a joint status report filed Thursday in the US District Court for the District of Delaware. Terms were not disclosed.
Cerence sued in May 2025, alleging Microsoft and Nuance "kept using text-to-speech software after their license expired" in 2024. Cerence was spun off from Nuance in 2019 and holds the TTS intellectual property; the two companies had inked a five-year licensing deal under which each needed the other's permission to re-license, and Nuance's rights lapsed when the agreement ran out.
The parties told the court they expect to finalize paperwork within 30 to 45 days and asked for a 60-day deadline. The filing did not detail the settlement.
