# Agentic SE Standard

> ASR-optimized speech enhancement with speech preservation for multi-speaker environments

The Standard Agentic SE (`AGENTIC_ST_SE`) model is designed to improve Automatic Speech Recognition (ASR) accuracy in noisy multi-speaker environments. Unlike traditional speech enhancement optimized for human perception, this model preserves the acoustic and phonetic information that ASR systems depend on, including distant human speech, while removing environmental noise.

## Hear the Difference

Removes environmental background noise while preserving distant human speech, ensuring ASR captures every speaker in multi-speaker environments where background conversations carry context.

### Performance Benchmarks

The following transcripts are generated from the audio samples above. The **Oracle Transcript** is the ground truth — the actual words spoken. The **Source Transcript** is the raw audio passed directly through the ASR system. The **Sanas Transcript** is the audio processed through the Sanas model first, then passed through the same ASR system. The **Word Error Rate (WER)** is calculated relative to the Oracle Transcript (0% WER), based on insertion, deletion, and substitution errors — bolded words below indicate these errors. WER percentage for each is shown at the bottom of the table.

#### Test Environment

* **Background**: Indoor environment with TV audio playing at moderate volume
* **ASR System**: Deepgram Nova3 Streaming

| hi my name is partho i'm here recording audio for snc dataset here i am uh playing the stock market news in moderate volume i'll give a pause for few seconds okay i will talk again for a few minutes then i will again give a pause so uh we would try to record in more different scenarios let's give a pause for another five seconds maybe okay uh they're showing advertisement now so i'm going to stop the recording here | hi my name is **barto** i'm here recording audio for s n c dataset here i am uh playing the stock market news in moderate volume i'll give a pause for a few seconds **wait for it till they're enter i think so not a taker right now in terms of like push move our goals but let's quickly slip into a topic** okay i will talk again for a few minutes then i will again give a pause so we would try to record in more different scenarios let's give a pause for another five seconds maybe okay they're showing advertisement now so i'm going to stop the recording here | hi my name is **barto** i'm here recording audio for s **m** c dataset here i am uh playing the stock market news in moderate volume i'll give a pause for few seconds okay i will talk again for a few minutes then i will again give a pause so we would try to record in more different scenarios let's give a pause for another five seconds maybe okay they're showing advertisement now so i'm going to stop the recording here |
