actiontecbr/falaai-api — PHP SDK for Conversation Intelligence, Speech Analytics & Compliance

Packagist version License: MIT CI Docs

Official PHP SDK for the FalaAI API — transcribe audio, analyze conversations and audit compliance (COPC CX, ISO 18295-1). Use each API independently or combine them into your own pipeline.

Analyze calls, contact-center recordings, voice notes, chat and email. Get speaker-separated transcripts, summaries, reasons, actions, sentiment and a compliance risk score.

Use any FalaAI API independently

FalaAI is a set of independent REST APIs. You do not need FalaAI Transcription to use FalaAI analysis or compliance auditing. If your application already has a transcript, send that text straight to the analysis APIs.

If you have... Use
Audio but no transcript SpeechApi — Transcription
An existing transcript AnalysisApi — Diagnostic
A transcript needing compliance analysis AnalysisApi — Risk Audit
An existing transcript needing both Diagnostic + Risk Audit
Your own STT provider (Whisper, Deepgram...) Skip FalaAI Transcription 
Your STT                             ->  FalaAI Diagnostic  ->  FalaAI Risk Audit
Telegram voice -> your STT           ->  FalaAI Risk Audit
3CX / Asterisk / Genesys transcript  ->  FalaAI Diagnostic  ->  FalaAI Risk Audit
CRM conversation                     ->  FalaAI Risk Audit

Install

composer require actiontecbr/falaai-api

Requires PHP 8.1+ (ext-curl, ext-json, ext-mbstring).

Quickstart

1. Get an API key

Create a free account and copy your fai_ key: https://falaai.action.tec.br/api/auth (or the Dashboard).

2. Set environment variables

FALAAI_BASE_URL=https://api01-falaai.action.tec.br
FALAAI_API_KEY=fai_xxxxxxxx

3. Transcribe a call (audio -> text)

<?php
require 'vendor/autoload.php';

use FalaAI\Configuration;
use FalaAI\Api\SpeechApi;

$config = (new Configuration())
    ->setHost(getenv('FALAAI_BASE_URL') ?: 'https://api01-falaai.action.tec.br')
    ->setAccessToken(getenv('FALAAI_API_KEY'));

[$transcription] = (new SpeechApi(null, $config))->createTranscriptionV1AudioTranscriptionsPostWithHttpInfo(
    new SplFileObject('call.mp3'),
    'falaai-transcribe-1',
    'pt',
    'call_202609271408'
);

echo json_encode($transcription, JSON_PRETTY_PRINT), PHP_EOL;

Expected response (abridged):

{
  "id": "tr-...",
  "object": "transcription",
  "model": "falaai-transcribe-1",
  "language": "por",
  "duration_seconds": 25.0,
  "text": "...",
  "dialog": "Speaker 1: [...] ...",
  "usage": { "audio_seconds": 25.0, "credits_consumed": 25, "processing_ms": 951 }
}

Only need analysis? Skip step 3 and call AnalysisApi with your own transcript (use the text field for a plain transcript).

4. Analyze or audit an existing transcript (no transcription needed)

<?php
use FalaAI\Configuration;
use FalaAI\Api\AnalysisApi;
use FalaAI\Model\DiagnosticRequest;
use FalaAI\Model\RiskAuditRequest;

$config = (new Configuration())
    ->setHost(getenv('FALAAI_BASE_URL'))
    ->setAccessToken(getenv('FALAAI_API_KEY'));
$analysis = new AnalysisApi(null, $config);

$transcript = 'Good morning, how can I help? I need to cancel my subscription.';

// 5 analyses in one call: summary, reason, action, topic, sentiment
[$diagnostic] = $analysis->createDiagnosticV1AnalyzeDiagnosticPostWithHttpInfo(
    new DiagnosticRequest(['text' => $transcript, 'language' => 'pt-BR', 'duration_seconds' => 81.46])
);

// Compliance risk score + violations + auditable report
[$audit] = $analysis->createRiskAuditV1AnalyzeRiskAuditPostWithHttpInfo(
    new RiskAuditRequest(['text' => $transcript, 'language' => 'pt-BR', 'response_language' => 'pt-BR', 'duration_seconds' => 81.46])
);

What is FalaAI API?

FalaAI API is an AI conversation-intelligence API for analyzing customer-service, contact-center, sales, messaging and other business conversations. It combines speech-to-text (with speaker diarization and audio-event detection), conversation analysis (summary, contact reason, action taken, topic classification, sentiment) and a compliance/risk audit against COPC CX and ISO 18295-1. Conversation content is processed and discarded (zero-storage).

What can you do with FalaAI?

  • Transcribe audio to text with speaker separation and audio events.
  • Diagnose a conversation: summary, reason, action taken, topic and sentiment.
  • Audit conversations: compliance risk score, detections/violations and an auditable HTML report.
  • Track usage, manage webhooks and email alerts, and health/version checks.

Use cases

  • Contact center / Quality - audit 100% of conversations instead of a sample.
  • Compliance / Legal - auditable evidence for audits and disputes.
  • CX / Operations - risk score, sentiment and reason per conversation.
  • BI / Data - typed JSON ready for your database or analytics stack.

Why FalaAI

  • Audit 100%, not a sample - every conversation gets a score, not a random QA sample.
  • Auditable by design - a compliance risk score with detections/violations and an HTML report you can hand to an auditor.
  • Credits, not tokens - you know exactly what each call costs (per second of audio, per character of text, per conversation). Monthly plans + non-expiring top-up packs.
  • Zero-storage - audio/text/results are processed and discarded; only usage/audit records remain. TLS in transit + at rest, per-account isolation (multitenancy), LGPD (you are the controller; Action Tec is the processor).
  • 3 native languages (PT/EN/ES) · start free (no card).
  • B2B ready - one Enterprise plan serves N clients, no per-user fee (ideal for ISVs).

Integrations

FalaAI is language-independent - integrate at any point of your pipeline (capture, transcription, analysis or audit). Common ecosystems:

Ecosystem How
PABX / telephony (3CX, Asterisk, Genesys) Send the recording to Transcribe, or the transcript to Diagnostic/Risk Audit.
CRM / ERP (Odoo, Salesforce, SAP Service Cloud, HubSpot) Attach the structured JSON (summary, reason, sentiment, risk score) to the record.
Contact center / QA (Zendesk, Twilio Flex, Take Blip) Batch-audit conversations and feed the score into your QA dashboard.
Chatbots / messaging (WhatsApp, Telegram, Microsoft Teams) Extract conversations from an export and analyze them.
BI / Data Typed JSON ready for your warehouse or analytics stack.

These are integration examples, not certified native integrations. Any platform can integrate through REST / cURL - the standard, language-independent path. Native ingestion connectors are on the roadmap.

BYOT - Bring Your Own Transcription

Already have speech-to-text (Whisper, Deepgram, AssemblyAI, your own)? Skip Transcription and send the text straight to Diagnostic and/or Risk Audit. You only pay for what you use.

Model IDs: falaai-transcribe-1, falaai-diagnostic-1, falaai-risk-audit-1.

Examples

Runnable examples in examples/: health.php, transcribe.php, diagnose.php, audit.php, whatsapp.php.

Authentication

Every request requires Authorization: Bearer fai_<your_key> — except the public endpoints (GET/HEAD /v1/health, GET /api/version). Set the key with Configuration::setAccessToken() (or FALAAI_API_KEY).

Error handling

Non-2xx responses throw FalaAI\ApiException.

<?php
use FalaAI\ApiException;

try {
    $health = (new \FalaAI\Api\HealthApi(null, $config))->healthCheck();
} catch (ApiException $e) {
    echo 'HTTP ' . $e->getCode() . ': ' . $e->getMessage();
}

Production usage

  • Store API keys in environment variables or a secret manager — never hard-code.
  • Reuse the Configuration across requests.
  • Handle FalaAI\ApiException explicitly.

Compatibility

Requirement Version
PHP 8.1+
API v1.21.51
