Many of these applications involve natural language classification, but deploying multiple specialized models creates a memory footprint challenge. We investigate: Can a single lightweight architecture solve multiple Speech-Adjacent (SA) classification tasks through reduction to a nuanced text similarity formulation? We propose AnySimLite, a lightweight similarity encoder that combines word-level and character-level channels. Together with a dataset transformation strategy, we evaluate AnySimLite across multiple SA classification tasks and show that it consistently achieves state-of-the-art (SOTA) or SOTA-competitive performance in few-shot settings while maintaining a low memory footprint. Even in the worst case, the performance drop remains below 7% while using $<\\frac{1}{250}^{\\mathrm{th}}$ of the model size of the SOTA qLLaMA_LoRA-7B baseline.", "url": "https://wpnews.pro/news/anysimlite-a-lightweight-few-shot-similarity-encoder-for-on-device-speech", "canonical_source": "https://arxiv.org/abs/2606.26452", "published_at": "2026-06-26 04:00:00+00:00", "updated_at": "2026-06-26 04:05:30.230696+00:00", "lang": "en", "topics": ["machine-learning", "natural-language-processing", "ai-research", "ai-products"], "entities": ["AnySimLite", "qLLaMA_LoRA-7B"], "alternates": {"html": "https://wpnews.pro/news/anysimlite-a-lightweight-few-shot-similarity-encoder-for-on-device-speech", "markdown": "https://wpnews.pro/news/anysimlite-a-lightweight-few-shot-similarity-encoder-for-on-device-speech.md", "text": "https://wpnews.pro/news/anysimlite-a-lightweight-few-shot-similarity-encoder-for-on-device-speech.txt", "jsonld": "https://wpnews.pro/news/anysimlite-a-lightweight-few-shot-similarity-encoder-for-on-device-speech.jsonld"}}
