Speak Upgrade & Migration

Overview

Upgrade Speak SDK versions, migrate between language learning platforms, and handle API version changes.

Prerequisites

Completed speak-install-auth setup
Valid API credentials configured
Understanding of Speak API patterns

Instructions

Current State

!npm list @speak/language-sdk 2>/dev/null || echo 'Speak SDK not installed'

Step 1: Check Current Version

npm list @speak/language-sdk
npm outdated @speak/language-sdk

Step 2: Upgrade SDK

npm install @speak/language-sdk@latest
npm test  # Run tests to verify compatibility

Step 3: API Version Migration

// Check for deprecated endpoints
const DEPRECATED_ENDPOINTS = [
  '/v1/lessons/start',      // Replaced by /v1/conversations/start
  '/v1/speech/score',       // Replaced by /v1/pronunciation/assess
];

// Migration map
const ENDPOINT_MIGRATION = {
  '/v1/lessons/start': '/v1/conversations/start',
  '/v1/speech/score': '/v1/pronunciation/assess',
};

Step 4: Platform Migration (from Duolingo/Babbel APIs)

// Map learning data between platforms
interface MigrationMapper {
  mapProficiencyLevel(source: string): 'beginner' | 'intermediate' | 'advanced';
  mapLanguageCode(source: string): string;
  mapProgress(source: any): SpeakProgress;
}

const duolingoMapper: MigrationMapper = {
  mapProficiencyLevel(crowns: string) {
    const c = parseInt(crowns);
    if (c < 3) return 'beginner';
    if (c < 6) return 'intermediate';
    return 'advanced';
  },
  mapLanguageCode: (code) => code, // Same ISO codes
  mapProgress: (duo) => ({
    vocabulary: duo.words_learned,
    level: duolingoMapper.mapProficiencyLevel(duo.crowns),
  }),
};

Post-Upgrade Verification

npm test
node -e "const s = require('@speak/language-sdk'); console.log('SDK version:', s.version || 'loaded OK')"

Output

Migration implementation complete
Speak API integration verified
Production-ready patterns applied

Error Handling

Error	Cause	Solution
401 Unauthorized	Invalid API key	Verify SPEAK_API_KEY environment variable
429 Rate Limited	Too many requests	Wait Retry-After seconds, use backoff
Audio format error	Wrong codec/sample rate	Convert to WAV 16kHz mono with ffmpeg
Session expired	Timeout after 30 min	Start a new conversation session

Next Steps

See speak-prod-checklist for production readiness.

Examples

Basic: Apply upgrade migration with default configuration for a standard Speak integration.

Advanced: Customize for production with error recovery, monitoring, and team-specific requirements.
