In this tutorial, you'll build a speech translation bot that analyzes your voice on a call and responds with a translated version in the language of your choice. Most speech translation services require an internet connection. However, the bot you’re going to build would just require your cellular network and as a result, could be used on even the simplest feature phones.

To build this, you'll use Twilio Programmable Voice and IBM Watson’s Speech Translation API.

今回のゲストは合同会社 selfreeの本間 皇成さんにお越しいただきました。2回目に登場いただきました八木さんと一緒にTwilioJP-UGで長期間に渡り活動されていらっしゃいます。そのほかにもHerokuコミュニティ（J-HUG）や個人Blog「ボクココ」を運営されています。

Une façon utile et répandue d’utiliser Twilio est de créer un numéro de téléphone qui redirige vers notre numéro de téléphone réel. On peut ainsi donner ce numéro à nos contacts professionnels et gérer nos appels business depuis notre portable. Notre numéro personnel est ainsi masqué derrière notre numéro Twilio.

Dans ce post je vais vous montrer comment créer un système de boîte vocale qui s’activera si vous êtes déjà en communication ou que vous ne prenez pas l’appel. Ce répondeur diffusera un message préenregistré, prendra le message de l’appelant et vous enverra un SMS avec un lien permettant d’y accéder. Encore plus simple que de devoir appeler sa boîte vocale.

Avant de commencer : Comment Twilio gère les appels

Lorsqu’un appel est émis vers votre numéro de téléphone Twilio, une requête HTTP est envoyée à une URL qui pointe vers un serveur web. Le serveur web reçoit et traite …
