ClearTone by SGO

ClearTone / Developers

ClearTone for Developers

ClearTone runs a small local connection on each person's computer. Your dialler, CRM or call guide can read the live transcript of both sides, the last call's notes and the coaching numbers, and switch ClearTone's features on or off, all without audio ever leaving the computer. SGO Call Caddie is built on exactly this connection.

What Your App Can Do With ClearTone

Live Transcript

Both sides of the call, line by line, about a third of a second behind the speaker. Show it in your app, search it or spot keywords.

Call Notes

The summary of the last call as soon as ClearTone has written it, ready to save to your CRM or show to the rep.

Coaching and Voicemail

Talk ratio, the current monologue, dead air and voicemail greetings, live, on ClearTone Pro.

Switches

Turn noise removal, auto volume or the live transcript on or off from your own screen, exactly as if the person clicked them.

Who the Call Is With

Send the name and CRM record of the person being called, so ClearTone files its notes on the right contact.

Private by Design

The connection only answers on the person's own computer and only to web addresses we have approved. Audio is never available through it.

A simple web connection at http://127.0.0.1:47820/cleartone on each computer running ClearTone. It speaks JSON and works from any web app, so there is nothing to install alongside it.

RequestWhat it does
GET /cleartone/statusIs ClearTone running, which switches are on, the microphone health, live coaching numbers and voicemail detection (Pro), Voice Studio, and the plan's features.
GET /cleartone/transcript?since=0Live transcript lines for both sides after line number since, plus the words being spoken right now. Needs the live transcript switched on.
GET /cleartone/notes/latestThe last call's title, summary and start time, when the note taker is on.
POST /cleartone/setSwitch features on or off, as if the person clicked them: mic_on, inc_on, agc_me, agc_them, transcript_on, and on Pro voice_on and voice.
POST /cleartone/contextTell ClearTone who the call is with (name, email, phone, company and the CRM record), so its notes are filed on the right record.

A Short Example

// Is ClearTone running on this computer?
const base = "http://127.0.0.1:47820/cleartone";
const status = await fetch(base + "/status").then(r => r.json());
if (status.running) console.log("ClearTone is on. Mic cleaning:", status.mic_on);

// Follow the live transcript
let last = 0;
setInterval(async () => {
  const t = await fetch(base + "/transcript?since=" + last).then(r => r.json());
  if (!t.on) return;
  t.segments.forEach(s => console.log(s.side, s.text));   // "me" or "them"
  last = t.last;
}, 500);

// Tell ClearTone who the call is with
await fetch(base + "/context", { method: "POST", headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ name: "Sarah Lee", company: "Acme Dental",
                         records: { hubspot: { module: "contacts", id: "1234" } } }) });

How Access Works

1. Tell Us Your Address

Email info@sgopeoplehub.com with the web address your app runs on and what you would like to build.

2. We Approve It

ClearTone only answers web addresses on its approved list, checked on every request. We add yours in the next app update.

3. Build and Test

While you build, ClearTone run from its source code also accepts requests from your own computer on port 8080.

The plan decides what is shared: on ClearTone Basic, coaching and voicemail numbers are not sent, and the live transcript and notes are shared only when the person has switched them on. The status always includes the plan's features, so your app can show what is available.

Pricing

Basic gives you crystal clear calls, Voice Studio and an AI note taker. Pro adds live coaching, translation, ClearTone Camera and team tools, with accent voices coming soon.

What Else We Offer

ClearTone is one part of what SGO PeopleHub does for businesses in the UK, Australia, the United States, Canada and New Zealand. Here is everything else we can help with.

Is there a developer kit or SDK?

Not yet. Today ClearTone offers the local connection described on this page, which any web app can use with a few lines of code. If you need something else, such as noise removal inside your own app, tell us what you are building.

Does it cost anything?

No. The connection is free. Each person using it needs ClearTone installed with a Basic or Pro plan.

Can my app get the call audio?

No. The connection never shares audio, only the transcript, notes, numbers and switches described here.

Can another website on the internet reach it?

No. It only answers on the person's own computer, and only to web addresses on ClearTone's approved list.

Which apps already use it?

SGO Call Caddie, the live call guide used by SGO PeopleHub's sales teams, uses it to show the live transcript, heard objections, voicemail detection and ClearTone's call notes.
