- 登录百度智能云账号
- https://console.bce.baidu.com/ai/?_=1654758432357&fromai=1#/ai/speech/app/list 访问此链接创建应用
- 创建完成后点击应用列表,记录API Key 和 Secret Key
- 使用API Key 和 Secret Key 获取token

- 使用hutool工具包调用百度长语音识别接口创建语音转换进程
<dependency>
<groupId>cn.hutool</groupId>
<artifactId>hutool-all</artifactId>
<version>5.7.19</version>
</dependency>
Map<String,Object> body = new HashMap<>();
body.put("speech_url","这里输入外网可访问的音频地址");
body.put("format","m4a");//音频格式支持["mp3", "wav", "pcm","m4a","amr"]单声道,编码 16bits 位深
body.put("pid","80001");
body.put("rate","16000");
String result = HttpUtil.post("https://aip.baidubce.com/rpc/2.0/aasr/v1/create?access_token=24.09fb9ae129423ec2f242048e4ad45fc6.2592000.1657344328.282335-26404843", JSONObject.valueToString(body));//需将获取到的token拼接到此处
if (result != null) {
JSONObject resultJson = new JSONObject(result);
System.out.println("resultJson"+resultJson);
}
- 将返回值中的task_id保存用于获取转换后的文字
//此处填写task_id多个视频需用逗号分割
String[] key = {"62a185bc72dec60c414b7f4b"};
Map<String,Object> bodys = new HashMap<>();

if (results != null) {
JSONObject resultJsons = new JSONObject(results);
JSONArray tasks_info = (JSONArray) resultJsons.get("tasks_info");

JSONObject task_result = (JSONObject) o.get("task_result");
JSONArray detailed_result = (JSONArray) task_result.get("detailed_result");
for (int i = 0; i < detailed_result.length(); i ++){
