Introducing Saaras V4, our most capable speech to text model yet. It delivers strong performance across both English and Indian languages, with better accuracy over a much wider range of speech. Saaras V4 was built with specific attention to noise, accents, dialects and mixed-language speech. Read more in the blog:

Saaras V4 is state of the art across all 22 Indian languages. 10 of these languages have no commercial alternative today.

Sarvam3 days ago

It also gets the lowest average word error rate across seven English benchmarks covering global accents, meetings, media and financial audio.

Sarvam3 days ago

Keyterm prompting is a new addition in Saaras V4, giving the model more context before transcription begins. Names, brands, product terms and specialised vocabulary can be provided as context, helping Saaras V4 recognise words that are uncommon, domain-specific or easy to mishear. This is especially useful in areas where a small transcription error can materially change the meaning.

Sarvam3 days ago

Saaras V4 preserves transcription accuracy across noisy audio. We evaluated Saaras V4 on Kathbath Noisy using LLM-WER, across speech affected by compression, clipping and background interference. Saaras V4 maintains substantially higher transcription accuracy under these conditions, with an error rate less than half that of Deepgram Nova-3 and GPT-4o Transcribe.

Sarvam3 days ago

Saaras V4 also supports five transcript formats for different applications. The formats let the same model serve very different workflows, from low-latency voice agents to verbatim transcripts for compliance and cleaner English for analysis.

What can Saaras V4 do now that it couldn't before? - Assamese helplines for Assam citizen services, disaster alerts, and health queries - Bodo helplines and panchayat bots for Bodoland / Assam local governance - Manipuri (Meitei) helplines for Manipur public services, hospitals, and education support - Combined Northeast voice desk covering Assamese + Bodo + Manipuri on one line - Santali tribal welfare apps in Jharkhand, Odisha, and Bengal - Santali mining / factory safety voice reporting in Jharkhand and nearby belts - Kashmiri citizen-service IVR and grievance bots for J&K - Dogri citizen-service IVR and local-body helpdesks for Jammu - Maithili agri advisories for Bihar / Mithila farmers - Maithili panchayat and ration / scheme query bots in north Bihar - Konkani banking IVR for Goa and the Konkan coast - Konkani insurance, UPI, and loan collections calls in Goa / coastal Karnataka / Maharashtra - Sanskrit temple recitation transcription and archive search Sanskrit education apps for pathshalas, universities, and exam practice - Sindhi community service, banking, and diaspora support lines - Nepali citizen and tourism helpdesks in Sikkim, Darjeeling, and border districts - Assamese + Nepali thinner-coverage upgrade for state portals that previously failed on dialect and code-mix - Low-resource language voice surveys for elections, health camps, and welfare schemes - Court / police verbatim records in Kashmiri, Dogri, Maithili, Santali, Bodo, or Manipuri - School and literacy apps that accept spoken answers in these languages instead of only Hindi or English Excited to see the ground level impact 🙌

kathbath, the noise benchmark, is read speech: a sample passed only if it exactly matched the prompt, and speakers were told to skip words they found hard to pronounce. that covers accent and channel. disordered speech is a different axis, and it's where asr is access.

Isoldegwow3 days ago

Finally a benchmark for people who start a sentence in English and finish it in Hindi.

Anil Pai3 days ago

Its v4 and still no word level timestamps. What is the use of segment level timestamps ? 🤷

This kind of robustness to accents and noise is what really makes STT usable in real world

Google presents AudioPaLM: A Large Language Model That Can Speak and Listen paper page: introduce AudioPaLM, a large language model for speech understanding and generation. AudioPaLM fuses text-based and speech-based language models, PaLM-2 [Anil et al., 2023] and AudioLM [Borsos et al., 2022], into a unified multimodal architecture that can process and generate text and speech with applications including speech recognition and speech-to-speech translation. AudioPaLM inherits the capability to preserve paralinguistic information such as speaker identity and intonation from AudioLM and the linguistic knowledge present only in text large language models such as PaLM-2. We demonstrate that initializing AudioPaLM with the weights of a text-only large language model improves speech processing, successfully leveraging the larger quantity of text training data used in pretraining to assist with the speech tasks. The resulting model significantly outperforms existing systems for speech translation tasks and has the ability to perform zero-shot speech-to-text translation for many languages for which input/target language combinations were not seen in training. AudioPaLM also demonstrates features of audio language models, such as transferring a voice across languages based on a short spoken prompt.

We have officially launched Fun-ASR1.5, a major update to our end-to-end speech recognition model. This release focuses on three core pillars: broader language coverage, language switching, and production-ready text output. Key Features: • Multilingual Support: Supports high-accuracy recognition for 30 languages across Asia, Europe, and the Middle East within a single model. • Language Switching: Handles mixed-language speech (Code-Switching) natively, automatically detecting and transcribing language shifts without the need for manual tagging. • Professional Text Output: Delivers "ready-to-use" text with smart punctuation and automatic formatting for dates, numbers, and currencies. Fun-ASR1.5 bridges the gap between raw audio and professional documentation, providing a reliable engine for global communication.
