NLB produces audio books, primarily in Bokmål (nb-NO), but voices for both Bokmål and Nynorsk (nb-NO) will be purchased. In the future, the number of media with synthetic speech will increase. Therefore a price model is needed which is beneficial for a large quantity of synthetic media and many users, and where the costs are predictable, even if the number of users increases. Currently, NLB’s users receive the synthetic speech which is pre-produced speech (currently synthesized on NLB’s servers).
NLB must upgrade to a new TTS system, including new voices. The renewal should include both Norwegian Bokmål and Nynorsk voices, and an English voice from the same service provider. The upgrading should comprise both a server based and a client based TTS system.
