# Inverse Text Normalization (ITN)
|
||
|
||
> **Note**:
|
||
> The modelscope pipeline supports all the models in [model zoo](https://modelscope.cn/models?page=1&tasks=inverse-text-processing&type=audio) to inference. Here we take the model of the Japanese ITN model as example to demonstrate the usage.
|
||
|
||
## Inference
|
||
|
||
### Quick start
|
||
#### [Japanese ITN model](https://modelscope.cn/models/damo/speech_inverse_text_processing_fun-text-processing-itn-ja/summary)
|
||
```python
|
||
from modelscope.pipelines import pipeline
|
||
from modelscope.utils.constant import Tasks
|
||
|
||
itn_inference_pipline = pipeline(
|
||
task=Tasks.inverse_text_processing,
|
||
model='damo/speech_inverse_text_processing_fun-text-processing-itn-ja',
|
||
model_revision=None)
|
||
|
||
itn_result = itn_inference_pipline(text_in='百二十三')
|
||
print(itn_result)
|
||
```
|
||
- read text data directly.
|
||
```python
|
||
rec_result = inference_pipeline(text_in='一九九九年に誕生した同商品にちなみ、約三十年前、二十四歳の頃の幸四郎の写真を公開。')
|
||
```
|
||
- text stored via url，example：https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/test_text/ja_itn_example.txt
|
||
```python
|
||
rec_result = inference_pipeline(text_in='https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/test_text/ja_itn_example.txt')
|
||
```
|
||
|
||
Full code of demo, please ref to [demo](https://github.com/alibaba-damo-academy/FunASR/tree/main/fun_text_processing/inverse_text_normalization)
|
||
|
||
### Modify Your Own ITN Model
|
||
The rule-based ITN code is open-sourced in [FunTextProcessing](https://github.com/alibaba-damo-academy/FunASR/tree/main/fun_text_processing), users can modify by their own grammar rules. After modify the rules, the users can export their own ITN models in local directory.
|
||
|
||
### Export ITN Model
|
||
Use the code in FunASR to export ITN model. An example to export ITN model to local folder is shown as below.
|
||
```shell
|
||
cd fun_text_processing/inverse_text_normalization/
|
||
python export_models.py --language ja --export_dir ./itn_models/
|
||
```
|
||
|
||
### Evaluate ITN Model
|
||
Users can evaluate their own ITN model in local directory. Here is an example:
|
||
```shell
|
||
python fun_text_processing/inverse_text_normalization/inverse_normalize.py --input_file ja_itn_example.txt --cache_dir ./itn_models/ --output_file output.txt --language=ja
|
||
```
|
||
|
||
### API-reference
|
||
#### Define pipeline
|
||
- `task`: `Tasks.inverse_text_processing`
|
||
- `model`: model name in [model zoo](https://modelscope.cn/models?page=1&tasks=inverse-text-processing&type=audio), or model path in local disk
|
||
- `output_dir`: `None` (Default), the output path of results if set
|
||
- `model_revision`: `None` (Default), setting the model version
|
||
|
||
#### Infer pipeline
|
||
- `text_in`: the input to decode, which could be:
|
||
- text bytes, `e.g.`: "一九九九年に誕生した同商品にちなみ、約三十年前、二十四歳の頃の幸四郎の写真を公開。"
|
||
- text file, `e.g.`: https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/test_text/ja_itn_example.txt
|
||
In this case of `text file` input, `output_dir` must be set to save the output results
