# An Overview of the IberSpeech-RTVE 2022 Challenges on Speech Technologies
## 6 Conclusions
Promising results in both speech-to-text transcription and speaker diarization tasks were obtained in some TV shows belonging to genres such as news, interviews, thematic magazines or daily magazines. However, there is still room for improvement when dealing with genres such as serial drama, reality shows and game shows. For text and speech alignment, more datasets are needed in order to cover all the problems associated to re-speaking where the re-speakers often end up paraphrasing, and more in-the-wild materials involving a wide range of acoustic conditions and transcript qualities should be used to assess the performance of text and speech alignment methods for leveraging loosely or partially transcribed audio resources as training data for ASR. With regard to the search on speech tasks (STD and QBe-STD), more research is needed to address the increased complexity posed by out-of-vocabulary terms and/or multi-word terms when compared to in-vocabulary and single-word terms. We are now actively preparing a new edition of the Albayzin evaluations, to be held along with the next IberSpeech conference in 2024. An extension of the RTVE database with new challenging audiovisual material will be released by April 2024, which will hopefully help to assess new developments in speech and language technologies.
