# 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
|
