In recent years, text-to-speech (TTS) models have advanced enormously. Month after month, new releases improved pronunciation, prosody, and overall audio quality. Unfortunately, most of those models were designed for English, or at best compatible with only a few languages. The tools available for generating Basque voices used to be quite limited: paid proprietary systems (such as Elhuyar’s neural TTS, developed by Orai), or older robotic voices that had clearly fallen behind. ...

Recently, the HiTZ center published the Latxa VL models. These models are based on Qwen3-VL models and possess vision capabilities. Currently, two sizes are available, both very small: models with 2B and 4B parameters. The tests presented below were performed with the 4B model. Models that know Basque Generally, models of such small size tend to only have the ability to answer decently in English. These Latxa VL models, however, have been trained to perform in Basque. ...
