CLOVA Voice TTS (Premium) APIを使用するユースケースを紹介します。
CLOVA Voice TTS (Premium)
変換対象のテキストと音色、スピード、感情などをパラメータで渡されて音声を合成する CLOVA Voice APIのユースケースを説明します。
Java
Javaベースの CLOVA Voice APIのサンプルコードは次の通りです。

String text = URLEncoder.encode("こんにちは。", "UTF-8"); // 13文字
String apiURL = "https://naveropenapi.apigw.ntruss.com/tts-premium/v1/tts";
URL url = new URL(apiURL);
HttpURLConnection con = (HttpURLConnection)url.openConnection();
con.setRequestMethod("POST");
con.setRequestProperty("X-NCP-APIGW-API-KEY-ID", clientId);

// post request
String postParams = "speaker=nara&volume=0&speed=0&pitch=0&format=mp3&text=" + text;

InputStream is = con.getInputStream();
int read = 0;
byte[] bytes = new byte[1024];
// ランダムな名前で mp3ファイルを作成
String tempname = Long.valueOf(new Date().getTime()).toString();
File f = new File(tempname + ".mp3");
f.createNewFile();
OutputStream outputStream = new FileOutputStream(f);
while ((read =is.read(bytes)) != -1) {
outputStream.write(bytes, 0, read);
}
is.close();
