ScotRail has launched a new AI onboard announcer using the voice of an employee following a row over a previous version.

Voiceover artist Gayanne Potter had complained that her voice was used without permission to help train the artificial intelligence announcer Iona.

She claims she was told her work for Swedish technology firm ReadSpeaker would be used for accessibility and e-learning software rather than wider commercial purposes.

Iona has now been replaced by another AI announcer, based on the voice of Paisley-based ScotRail employee Vannessa Sloan.

Ms Potter previously told BBC Scotland News it had been a surprise to hear a "dreadful" robotic version of herself.
