 UnitY-Small-S2T is a pruned version of UnitY-Small without 2nd pass unit decoding.
 
-Note: If using pytorch runtime in python, only **pytorch<=1.11.0** is supported for **UnitY-Small(281M)**. We tested UnitY-Small-S2T(235M), it works with later versions.

 ## Inference
 To use exported model, users don't need seamless_communication or fairseq2 dependency.
 
 ```python
 import torchaudio
 import torch
+
 audio_input, _ = torchaudio.load(TEST_AUDIO_PATH) # Load waveform using torchaudio
 
 s2t_model = torch.jit.load("unity_on_device_s2t.ptl") # Load exported S2T model
-text = s2t_model(audio_input, tgt_lang=TGT_LANG) # Forward call with tgt_lang specified for ASR or S2TT
-print(f"{lang}:{text}")
 
-s2st_model = torch.jit.load("unity_on_device.ptl")
-text, units, waveform = s2st_model(audio_input, tgt_lang=TGT_LANG) # S2ST model also returns waveform
-print(f"{lang}:{text}")
-torchaudio.save(f"{OUTPUT_FOLDER}/{lang}.wav", waveform.unsqueeze(0), sample_rate=16000) # Save output waveform to local file
+with torch.no_grad():
+    text = s2t_model(audio_input, tgt_lang=TGT_LANG) # Forward call with tgt_lang specified for ASR or S2TT
+
+print(text) # Show text output 
 ```
 
 Also running the exported model doesn't need python runtime. For example, you could load this model in C++ following [this tutorial](https://pytorch.org/tutorials/advanced/cpp_export.html), or building your own on-device applications similar to [this example](https://github.com/pytorch/ios-demo-app/tree/master/SpeechRecognition)
