Human starts to plan answer 2 seconds before question end

Quite an obvious but so ignored by industry before. There is certainly no need to clone from 3 seconds

You can now create an instant voice clone from up to 2 minutes of reference audio, compared with 20 seconds before.

The longer sample gives the model much more information about the voice, including phonemes, intonation, pauses, rhythm, pacing, emphasis, emotion, and speaking style.

The result:
• Higher voice similarity
• Greater consistency, especially across longer sentences
• Better pronunciation coverage
• More natural prosody
• Better preservation of speaking style

Ready to Speak: Aligning LLMs for TTS-Friendly Text Generation

Thibaut Thonet, Jos Rozen, Laurent Besacier

Current Large Language Models (LLMs) are primarily optimized for written text, often producing outputs that are grammatically correct and helpful yet poorly suited for spoken delivery via Text-to-Speech (TTS). In this work, we study how to make LLMs natively generate TTS-friendly text, which we frame as a preference alignment problem: instead of relying on downstream rewriting modules, we directly align LLMs to generate text optimized for spoken delivery. We introduce two preference datasets spanning different target domains, CORA and Recipe, which contain paired TTS-friendly and TTS-unfriendly responses. We further propose an evaluation suite combining a pattern-based heuristic metric, a TTS→ASR evaluation pipeline, and a MUSHRA listening study with human judges. Our experiments compare the recently proposed Feature-aware Sampling and Tuning (FaST) framework -- leveraging interpretable features instead of a black-box reward model -- against an array of alignment baselines on the TTS-friendly generation task. Notably, we found that FaST achieves the best overall tradeoff between TTS-friendliness and helpfulness across various settings. We also identified a strong correlation between our different metrics, highlighting the ability to reliably assess TTS-friendliness via an efficient heuristic.

Bodhan AI together with AI4Bharat recently released a great update on Indic ASR

https://bodhan.ai/research/blogs/indic-transcribe

ParsVoice, the largest open-source Persian speech dataset, along with a TTS model and an open-source processing pipeline is released.

The paper has also been accepted as a main conference paper at EMNLP 2026.

AuK is a 1.5B foundation model for speech generation and editing. Trained on millions of hours of diverse audio data, AuK supports zero-shot and instruction-based TTS, content and acoustic editing, paralinguistic editing, speech enhancement, and source separation through a unified natural-language instruction interface.

Suplime results on Russian telephony data, good results, first place, large model is better than Diarizen

A bit slow though

Interesting TTS, claims 14ms TTFA

My friend Miro recommended me Orukeet model

https://github.com/Oruk-AI/orukeet

https://arxiv.org/abs/2609.10054

it is indeed a good parakeet improvement, about 10% better. Interesting that people left scaling and return back to in-depth architecture analysis.

Oruk.AI does some other nice things, for example a visualization of emotion representation in different layers of speech models

We see a huge decline of the interest in speech technology in China but a rise in Europe and India. Recently I discussed it with one of my Chinese friends - he confirms that nobody is interested anymore in plain speech. It has to be multimodal - video, music generation, etc.

"百闻不如一见" — hearing something a hundred times is worse than seeing it once

China is ahead of time here.
