# Speak SDK Patterns ## Overview Production patterns for Speak language learning API: conversation sessions, pronunciation assessment, audio preprocessing, and batch operations. ## Prerequisites - Completed `speak-install-auth` setup - Valid API credentials configured - ffmpeg installed for audio processing ## Instructions ### Pattern 1: Conversation Session Manager ```typescript class ConversationManager { private client: SpeakClient; private sessions: Map<string, SessionState> = new Map(); async startLesson(language: string, scenario: string, level: string) { const session = await this.client.startConversation({ scenario, language, level, nativeLanguage: 'en', }); this.sessions.set(session.id, { turns: [], startTime: Date.now(), language, }); return session; } async submitResponse(sessionId: string, audioPath: string) { const turn = await this.client.sendTurn(sessionId, { audioPath }); this.sessions.get(sessionId)?.turns.push(turn); return turn; } async endAndReport(sessionId: string) { const summary = await this.client.endSession(sessionId); const state = this.sessions.get(sessionId)!; return { ...summary, duration: (Date.now() - state.startTime) / 1000, totalTurns: state.turns.length, avgPronunciation: state.turns.reduce((s, t) => s + (t.pronunciationScore || 0), 0) / state.turns.length, }; } } ``` ### Pattern 2: Audio Preprocessor ```typescript import { exe...
