C++音频转中文汉字全部代码

抱歉，C++无法直接将音频转换为中文汉字，需要使用语音识别技术。以下是一个使用百度语音识别API进行语音识别的示例代码：

#include <iostream>
#include <fstream>
#include <string>
#include <cstring>
#include <cstdlib>
#include <curl/curl.h>
#include <json/json.h>

using namespace std;

// 百度语音识别API参数
const string API_KEY = "YOUR_API_KEY";
const string SECRET_KEY = "YOUR_SECRET_KEY";
const string API_URL = "https://vop.baidu.com/server_api";

// 读取音频文件
bool readAudioFile(const string& filename, string& audio) {
  ifstream file(filename.c_str(), ios::binary);
  if (!file.is_open()) {
    cerr << "Error: cannot open audio file " << filename << endl;
    return false;
  }

  file.seekg(0, ios::end);
  int length = file.tellg();
  file.seekg(0, ios::beg);

  audio.resize(length);
  file.read(&audio[0], length);
  file.close();

  return true;
}

// 发送HTTP请求
size_t sendHttpRequest(const string& url, const string& audio, string& response) {
  CURL *curl = curl_easy_init();
  if (!curl) {
    cerr << "Error: cannot initialize curl" << endl;
    return 0;
  }

  struct curl_slist *headers = NULL;
  headers = curl_slist_append(headers, "Content-Type: audio/wav; rate=16000");
  headers = curl_slist_append(headers, "Content-Length: " + to_string(audio.size()));

  curl_easy_setopt(curl, CURLOPT_URL, url.c_str());
  curl_easy_setopt(curl, CURLOPT_POST, 1L);
  curl_easy_setopt(curl, CURLOPT_POSTFIELDS, audio.c_str());
  curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, audio.size());
  curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
  curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, [](char *ptr, size_t size, size_t nmemb, string *data){
    data->append(ptr, size * nmemb);
    return size * nmemb;
  });
  curl_easy_setopt(curl, CURLOPT_WRITEDATA, &response);

  CURLcode res = curl_easy_perform(curl);
  if (res != CURLE_OK) {
    cerr << "Error: curl perform failed: " << curl_easy_strerror(res) << endl;
  }

  long httpCode = 0;
  curl_easy_getinfo(curl, CURLINFO_RESPONSE_CODE, &httpCode);

  curl_slist_free_all(headers);
  curl_easy_cleanup(curl);

  return httpCode;
}

// 解析JSON结果
string parseJsonResult(const string& jsonResult) {
  Json::Value root;
  Json::Reader reader;
  if (!reader.parse(jsonResult, root)) {
    cerr << "Error: parse JSON result failed" << endl;
    return "";
  }

  string result = "";
  if (root.isMember("result") && root["result"].isArray()) {
    for (Json::Value::ArrayIndex i = 0; i < root["result"].size(); i++) {
      result += root["result"][i].asString();
    }
  }

  return result;
}

int main(int argc, char *argv[]) {
  if (argc != 2) {
    cerr << "Usage: " << argv[0] << " <audio file>" << endl;
    return EXIT_FAILURE;
  }

  string filename = argv[1];
  string audio;
  if (!readAudioFile(filename, audio)) {
    return EXIT_FAILURE;
  }

  string url = API_URL + "?cuid=123456789&dev_pid=1536&token=";
  url += "24.0e5c8d9f210c0883bd5f6f4b1b3b72b.2592000.1627789015.282335-24469880";

  string response;
  if (sendHttpRequest(url, audio, response) != 200) {
    return EXIT_FAILURE;
  }

  string result = parseJsonResult(response);
  cout << result << endl;

  return EXIT_SUCCESS;
}

请注意替换API_KEY和SECRET_KEY为您自己的密钥。此代码仅供参考，不保证能够完全运行
