| -- 更新阿里云流式ASR配置说明
| UPDATE `ai_model_config` SET
| `doc_link` = 'https://nls-portal.console.aliyun.com/',
| `remark` = '阿里云流式ASR配置说明：
| 1. 阿里云ASR和阿里云(流式)ASR的区别是：阿里云ASR是一次性识别，阿里云(流式)ASR是实时流式识别
| 2. 流式ASR具有更低的延迟和更好的实时性，适合语音交互场景
| 3. 需要在阿里云智能语音交互控制台创建应用并获取认证信息
| 4. 支持中文实时语音识别，支持标点符号预测和逆文本规范化
| 5. 需要网络连接，输出文件保存在tmp/目录
| 申请步骤：
| 1. 访问 https://nls-portal.console.aliyun.com/ 开通智能语音交互服务
| 2. 访问 https://nls-portal.console.aliyun.com/applist 创建项目并获取appkey
| 3. 访问 https://nls-portal.console.aliyun.com/overview 获取临时token（或配置access_key_id和access_key_secret自动获取）
| 4. 如需动态token管理，建议配置access_key_id和access_key_secret
| 5. max_sentence_silence参数控制断句检测时间（毫秒），默认800ms
| 如需了解更多参数配置，请参考：https://help.aliyun.com/zh/isi/developer-reference/real-time-speech-recognition
