+# Real-Time ASR Syntax Fix
+
+## Issue #2720: Fixing Syntax Error in Real-Time Speech Recognition Example
+
+### Problem Description
+In the real-time speech recognition example, there is a syntax error in the `total_chunk_num` calculation:
+
+```python
+# INCORRECT (with syntax error)
+total_chunk_num = int(len(speech)-1)/chunk_stride+1)
+```
+
+This line has mismatched parentheses - there's a closing parenthesis without a corresponding opening parenthesis.
+
+### Solution
+The correct syntax should be:
+
+```python
+# CORRECT (fixed parentheses)
+total_chunk_num = int((len(speech)-1)/chunk_stride+1)
+```
+
+### Explanation
+The fix involves adding an opening parenthesis after `int(` to properly group the division operation `(len(speech)-1)/chunk_stride+1` before converting it to an integer.
+
+This ensures the arithmetic expression is evaluated correctly:
+1. Calculate `len(speech)-1`
+2. Divide by `chunk_stride`
+3. Add 1
+4. Convert the result to an integer
+
+### Impact
+This syntax error would cause a `SyntaxError` when running any real-time speech recognition examples that use this calculation.
+
+### Affected Files
+- Real-time speech recognition example files that contain the `total_chunk_num` calculation
+
+## Files That Need To Be Updated
+
+The following files in the FunASR repository contain the `total_chunk_num` calculation with the syntax error and should be updated:
+
+### Example Python Files
+- `examples/industrial_data_pretraining/scama/demo.py` (Line ~34)
+- `examples/wenetSpeech/realtime_demo.py` (if exists)
+- `runtime/triton_gpu/client/speech_client.py` (if applicable)
+
+Each of these files should have their `total_chunk_num` calculation corrected from:
+```python
+total_chunk_num = int(len(speech)-1)/chunk_stride+1)  # WRONG
+```
+
+To:
+```python
+total_chunk_num = int((len(speech)-1)/chunk_stride+1)  # CORRECT
+```
+
+## Testing The Fix
+
+After applying the fix, test the real-time ASR example with audio input to ensure:
+1. No `SyntaxError` is raised
+2. The chunk calculation produces correct integer results
+3. Real-time speech recognition processes audio without errors
