调用火山云的语音生成TTS和语音识别STT

首先需要去火山云的控制台开通TTS和STT服务语音技术 (volcengine.com)

火山这里都提供了免费的额度可以使用

我这里是使用了java来调用API

目前我还了解到阿里的开源项目SenseVoice（STT）和CosyVoice(TTS)非常的不错，但是都是使用Python开发的。可以做到说话情绪的识别，感兴趣可以去github上了解一下。


TTS（首先需要导入它给的类）

package com.erroright.backend_server_java.pojo.util;import java.util.UUID;public class TtsRequest {public static final String APP_ID = "控制台的APPID";public static final String CLUSTER = "";public static final String Token = "";public static final String VoiceType = "BV001_streaming";//生成声音的选择（如果生成语音报错，就是你没开通这个音色的权限）public static final String Emotion = "angry";//语气public TtsRequest() {}public TtsRequest(String text) {this.request.text = text;}private App app = new App();private User user = new User();private Audio audio = new Audio();private Request request = new Request();public App getApp() {return app;}public void setApp(App app) {this.app = app;}public User getUser() {return user;}public void setUser(User user) {this.user = user;}public Audio getAudio() {return audio;}public void setAudio(Audio audio) {this.audio = audio;}public Request getRequest() {return request;}public void setRequest(Request request) {this.request = request;}public class App {private String appid = APP_ID;private String token = Token; // 目前未生效，填写默认值：access_tokenprivate String cluster = CLUSTER;public String getAppid() {return appid;}public void setAppid(String appid) {this.appid = appid;}public String getToken() {return token;}public void setToken(String token) {this.token = token;}public String getCluster() {return cluster;}public void setCluster(String cluster) {this.cluster = cluster;}}public class User {private String uid = "388808087185088"; // 目前未生效，填写一个默认值就可以public String getUid() {return uid;}public void setUid(String uid) {this.uid = uid;}}public class Audio {private String voice_type = VoiceType;private String encoding = "wav";private float speed_ratio = 1.0F;private float volume_ratio = 10;private float pitch_ratio = 10;private String emotion = Emotion;public String getVoice_type() {return voice_type;}public void setVoice_type(String voice_type) {this.voice_type = voice_type;}public String getEncoding() {return encoding;}public void setEncoding(String encoding) {this.encoding = encoding;}public float getSpeedRatio() {return speed_ratio;}public void setSpeedRatio(int speed_ratio) {this.speed_ratio = speed_ratio;}public float getVolumeRatio() {return volume_ratio;}public void setVolumeRatio(int volume_ratio) {this.volume_ratio = volume_ratio;}public float getPitchRatio() {return pitch_ratio;}public void setPitchRatio(int pitch_ratio) {this.pitch_ratio = pitch_ratio;}public String getEmotion() {return emotion;}public void setEmotion(int emotion) {this.emotion = String.valueOf(emotion);}}public class Request {private String reqid = UUID.randomUUID().toString();private String text;private String text_type = "plain";private String operation = "query";public String getReqid() {return reqid;}public void setReqid(String reqid) {this.reqid = reqid;}public String getText() {return text;}public void setText(String text) {this.text = text;}public String getText_type() {return text_type;}public void setText_type(String text_type) {this.text_type = text_type;}public String getOperation() {return operation;}public void setOperation(String operation) {this.operation = operation;}}
}

调用代码

package com.erroright.backend_server_java.util;import com.alibaba.fastjson.JSON;
import com.erroright.backend_server_java.pojo.util.TtsRequest;
import lombok.extern.slf4j.Slf4j;
import okhttp3.*;
import org.springframework.stereotype.Component;import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Base64;@Component
@Slf4j
public class TtsHttpClient {public static final String API_URL = "https://openspeech.bytedance.com/api/v1/tts";public static final String ACCESS_TOKEN = "填入火山云开通项目的Token";public static byte[] getTts(String content) throws IOException {log.info("TTS生成："+content);TtsRequest ttsRequest = new TtsRequest(content);String json= JSON.toJSONString(ttsRequest);OkHttpClient client = new OkHttpClient();RequestBody body = RequestBody.create(json, MediaType.get("application/json; charset=utf-8"));Request request = new Request.Builder().url(API_URL).post(body).header("Authorization", "Bearer; " + ACCESS_TOKEN).build();try (Response response = client.newCall(request).execute()) {String TtsRresponse=response.body().string();// 提取 "data" 字段的值String data = TtsRresponse.split("\"data\":\"")[1].split("\"")[0];//保存生成的文件try (FileOutputStream fos = new FileOutputStream("output.wav")) {fos.write(Base64.getDecoder().decode(data));}// 解码 Base64 数据return Base64.getDecoder().decode(data);}}}

STT(导入类，在官方文档中是三个类，为了在springBoot中封装，分开了一个)
