+# VoicePeak API Service
+このプロジェクトは、VoicePeakを使用して音声を生成し、生成された音声データを提供するAPIサーバーです。
+PythonのFlaskフレームワークを使用し、Ubuntu上で動作します。
+
+## プロジェクト構成
+```
+/path/to/your/project
+├── app.py
+├── requirements.txt
+├── venv/
+└── voicepeak-api.service
+```
+
+## 前提条件
+- Ubuntuがインストールされたシステム
+- VoicePeakがホストOSにインストールされ、動作すること
+
+## セットアップ手順
+### 1. リポジトリのクローン
+リポジトリをクローンします。
+
+```bash
+git clone *******
+```
+
+### 2. Pythonの仮想環境を作成
+仮想環境を作成し、必要なパッケージをインストールします。
+
+```bash
+# 仮想環境の作成
+python3 -m venv venv
+
+# 仮想環境のアクティベート
+source venv/bin/activate
+
+# 必要なパッケージのインストール
+pip install -r requirements.txt
+```
+
+### 3. Systemdサービスの設定
+`voicepeak-api.service`ファイルを適切な内容に編集します。
+`voicepeak-api.service`ファイルをシステムのsystemdサービスディレクトリにシンボリックリンクを作成します。
+
+```bash
+sudo ln -s /path/to/your/project/voicepeak-api.service /etc/systemd/system/voicepeak-api.service
+```
+
+### 4. サービスのリロードと起動
+
+systemdに新しいサービスを認識させ、サービスを起動します。
+
+```bash
+# systemdデーモンのリロード
+sudo systemctl daemon-reload
+
+# サービスの開始
+sudo systemctl start voicepeak-api.service
+
+# サービスの有効化（再起動後も自動で起動するようにする）
+sudo systemctl enable voicepeak-api.service
+```
+
+### 5. 動作確認
+
+サービスが正常に起動しているか確認します。
+
+```bash
+sudo systemctl status voicepeak-api.service
+```
+
+## 使用方法
+
+サービスが正常に起動している場合、以下のようにリクエストを送信して音声を生成できます。
+
+```bash
+curl -X POST http://127.0.0.1:5000/generate_voice -H "Content-Type: application/json" -d '{"text": "こんにちは"}' --output output.wav
+```
