    Announcing Dual-channel Call Recordings by Default Programmable Voice Dual-channel by default header

    We’re excited to announce that voice recordings are now recorded and stored at Twilio in dual-channel by default at no additional cost, starting today for new accounts and being rolled out for all accounts.

    With this change, two-party audio files of call recordings will now have two channels and contain the audio from each call leg in a separate channel, enabling you to process the individual participants of the call recorded for much better speaker accuracy. Previously, you needed to specify dual-channel to record each participant in a separate channel, while all audio mixed in a single channel was the default behavior.

    As part of this release, dual-channel is now the same price as mono-channel storage because we want all of our voice customers to benefit from dual-channel recordings.

    The value of dual-channel recordings

    Call recordings are often used to understand the customer journey and satisfaction, collect evidence and …

    Twilio Voiceの通話録音向け外部ストレージ機能リリースのお知らせ External Storage Support Programmable Voice JP

    この記事はRamón Ulldemolinsこちらで公開した記事(英語)を日本語化したものです。

    Twilio Voiceサービスの通話録音ファイルをお客様企業が管理するAWS S3バケット(ストレージ)に保存できるようになったことをお知らせします。


    従来この構成を実現するためには、通話録音が完了したときに通知されるWebhookをrecordingStatusCallbackを通じて設定し、録音ファイルをダウンロードを行います。その後、独自ストレージに保存してから、Twilioクラウド上の録音ファイルを削除する必要がありました。今回の機能により、録音メディアを保存するストレージとして自社が管理するAWS S3バケットを指定することで、追加のソフトウェア開発や、各録音のダウンロードやアップロードするための追加APIリクエスト(プログラム処理)が必要なく、各録音ファイルを独自に保存できるようになりました。

    Announcing External AWS S3 Storage Support for Voice Recordings External Storage Support Programmable Voice

    We’re excited to announce that you can now store your voice recordings in your own AWS S3 bucket.

    By default, the media associated with a voice recording is stored within Twilio. Although this is convenient for many customers, there are customers who want their recordings to be stored on their systems for additional processing, storage, or compliance reasons.

    To achieve this in the past, customers have had to set up a webhook to be notified when a recording is completed with the recordingStatusCallback, download the recording, save it into their storage and then delete it from Twilio. Starting today, it's now possible to specify an AWS S3 bucket where media must be stored without the need for additional software development and additional API requests to programmatically download and upload each recording independently.

    The release of this feature represents Twilio’s commitment to serve their customers and help them meet their …

    Announcing Single Party Call Recordings Announcing Single Party Recordings on Twilio Programmable Voice

    We’re excited to announce that we’ve extended voice recording capabilities with single party recording to allow developers to programmatically record only one side of a call. Prior to this release, Twilio’s voice recordings captured all audio from a call, regardless if the file contained one or two channels. Using this new feature, you now have the flexibility to record exactly what you want, all while meeting your specific privacy and compliance needs.

    Whether it's recording only what your support agent says to customers, or what your salesperson says to prospects — the choice is now yours.

    The value of single party recordings

    Call centers look to monitor and improve the performance of their agents using recorded calls as reference for training and to gather insights driven by AI/ML technologies to improve the overall quality of their service. However, due to the global tightening of privacy policies, data collection procedures often …

    Deliver voice notifications over the phone in just three steps Deliver voice notifications over the phone in just three steps

    School closures, emergency notifications, and severe weather alerts are examples of time-sensitive automated phone calls that consumers care about. However, creating notification solutions can be difficult. We often find organizations face roadblocks while developing flexible solutions that scale to accommodate high-volumes or new regions, reliably. Building these types of solutions takes time and careful consideration. To aid in developer education, we are excited to announce that we are open sourcing a Voice Notification App built in ReactJS for the Web. This reference app can be deployed to Heroku in minutes and demonstrates how to leverage Programmable Voice APIs to create a voice notification system to make calls to your customers to deliver time-sensitive messages.

    You can use this reference app as a starting point for your voice notification use case.

    This application is available on GitHub under the Apache 2.0 license. See the source code repo here:
