I just finished the first year of my PhD. Rather than just share my own perspective, I sat down with 7 other students in my cohort and talked with them about their experiences in depth. In my new post, I share some of our biggest lessons: jonathanivey.github.io/2026/…

I will present MedExpert, a clinician-annotated Factuality and Completeness dataset with Severity levels for Medical Chatbot Evaluation at ML4H in San Diego today. Happy to chat from Dec 1 to 3! See paper at: openreview.net/pdf?id=rkLAzD… @mdredze @Alexir563 @jhuclsp @SonalSSJ

We introduce WaltzRL🎶, a multi-agent RL framework that treats LLM safety as a positive-sum game between conversation & feedback agents. It strikes an elegant balance between helpfulness & harmlessness, boosting safety & reduces overrefusals without degrading capabilities!
💃New Multi-Agent RL Method: WaltzRL💃 📝: arxiv.org/abs/2510.08240 - Makes LLM safety a positive-sum game between a conversation & feedback agent - At inference feedback is adaptive, used when needed -> Improves safety & reduces overrefusals without degrading capabilities! 🧵1/5

#Lhotse now supports annotating audio files with OpenAI's #Whisper! Here's a quick demo I created in 10 mins to transcribe the first 100 recordings from VoxCeleb. See PR from @PiotrZelasko: github.com/lhotse-speech/lho… Here's the sample audio: tinyurl.com/3vjxnubk

Any #SpeechProc person who hasn't been living under a rock for the last few years has definitely come across the "transducer" model (formerly known as the RNN-Transducer). They look like this: (1/n)

On that note, maybe I should do Twitter Bytes to summarize works in "Adversarial Attacks and Countermeasures" as these topics are not very well-known in the speech community? ♥️= upvote the idea

Replying to @rdesh26
Thanks @rdesh26 for tagging. Adversarial attacks cause havoc on both Speech and Speaker Recognition systems! Our team is working on how to protect against them and have many cool papers. Will follow up on details in the thread🧵
