Speech Recognition:

• Voice commands and controls
• Voice-to-text input
• Continuous dictation
• Command detection

Text-to-Speech:

• Reading content aloud
• Voice feedback and notifications

• Voice selection and customization

Voice UI:

• Voice-first interfaces
• Accessibility features
• Hands-free controls
• Voice search

Web Speech API Basics

Speech Recognition

// hooks/useSpeechRecognition.ts
'use client'
import { useState, useEffect, useRef } from 'react'

interface SpeechRecognitionOptions {
  continuous?: boolean
  language?: string
  onResult?: (transcript: string) => void
  onError?: (error: string) => void
}

export function useSpeechRecognition({
  continuous = false,
  language = 'en-US',
  onResult,
  onError
}: SpeechRecognitionOptions = {}) {
  const [isListening, setIsListening] = useState(false)
  const [transcript, setTranscript] = useState('')
  const recognitionRef = useRef<SpeechRecognition | null>(null)

  useEffect(() => {
    if (typeof window === 'undefined') return

    const SpeechRecognition = window.SpeechRecognition || window.webkitSpeechRecognition

    if (!SpeechRecognition) {
      console.warn('Speech recognition not supported')
      return
    }

    const recognition = new SpeechRecognition()
    recognition.continuous = continuous
    recognition.lang = language
    recognition.interimResults = true

    recognition.onresult = event => {
      const transcript = Array.from(event.results)
        .map(result => result[0].transcript)
        .join('')

      setTranscript(transcript)
      onResult?.(transcript)
    }

    recognition.onerror = event => {
      console.error('Speech recognition error:', event.error)
      onError?.(event.error)
      setIsListening(false)
    }

    recognition.onend = () => {
      setIsListening(false)
    }

    recognitionRef.current = recognition

    return () => {
      recognition.stop()
    }
  }, [continuous, language, onResult, onError])

  const start = () => {
    if (recognitionRef.current && !isListening) {
      recognitionRef.current.start()
      setIsListening(true)
    }
  }

  const stop = () => {
    if (recognitionRef.current && isListening) {
      recognitionRef.current.stop()
      setIsListening(false)
    }
  }

  return { isListening, transcript, start, stop }
}

Usage:

'use client'
import { useSpeechRecognition } from '@/hooks/useSpeechRecognition'

export function VoiceInput() {
  const { isListening, transcript, start, stop } = useSpeechRecognition({
    onResult: (text) => console.log('Recognized:', text)
  })

  return (
    <div>
      <button onClick={isListening ? stop : start}>
        {isListening ? '🔴 Stop' : '🎤 Start Listening'}
      </button>
      <p>{transcript}</p>
    </div>
  )
}

Text-to-Speech

// hooks/useSpeechSynthesis.ts
'use client'
import { useState, useEffect } from 'react'

export function useSpeechSynthesis() {
  const [voices, setVoices] = useState<SpeechSynthesisVoice[]>([])
  const [speaking, setSpeaking] = useState(false)

  useEffect(() => {
    if (typeof window === 'undefined') return

    const loadVoices = () => {
      const availableVoices = window.speechSynthesis.getVoices()
      setVoices(availableVoices)
    }

    loadVoices()
    window.speechSynthesis.onvoiceschanged = loadVoices
  }, [])

  const speak = (
    text: string,
    options?: {
      voice?: SpeechSynthesisVoice
      rate?: number
      pitch?: number
      volume?: number
    }
  ) => {
    if (typeof window === 'undefined') return

    const utterance = new SpeechSynthesisUtterance(text)

    if (options?.voice) utterance.voice = options.voice
    if (options?.rate) utterance.rate = options.rate // 0.1 - 10
    if (options?.pitch) utterance.pitch = options.pitch // 0 - 2
    if (options?.volume) utterance.volume = options.volume // 0 - 1

    utterance.onstart = () => setSpeaking(true)
    utterance.onend = () => setSpeaking(false)
    utterance.onerror = () => setSpeaking(false)

    window.speechSynthesis.speak(utterance)
  }

  const cancel = () => {
    if (typeof window !== 'undefined') {
      window.speechSynthesis.cancel()
      setSpeaking(false)
    }
  }

  return { speak, cancel, speaking, voices }
}

Usage:

'use client'
import { useSpeechSynthesis } from '@/hooks/useSpeechSynthesis'

export function TextToSpeech() {
  const { speak, cancel, speaking, voices } = useSpeechSynthesis()
  const [text, setText] = useState('Hello, how can I help you today?')

  return (
    <div>
      <textarea
        value={text}
        onChange={(e) => setText(e.target.value)}
        rows={4}
      />

      <button
        onClick={() => speak(text)}
        disabled={speaking}
      >
        {speaking ? 'Speaking...' : '🔊 Speak'}
      </button>

      <button onClick={cancel} disabled={!speaking}>
        ⏹️ Stop
      </button>

      <select onChange={(e) => {
        const voice = voices.find(v => v.name === e.target.value)
        if (voice) speak(text, { voice })
      }}>
        {voices.map((voice) => (
          <option key={voice.name} value={voice.name}>
            {voice.name} ({voice.lang})
          </option>
        ))}
      </select>
    </div>
  )
}

Voice Commands

Command Detection

'use client'
import { useSpeechRecognition } from '@/hooks/useSpeechRecognition'
import { useEffect } from 'react'

interface Command {
  phrase: string | RegExp
  action: () => void
}

export function VoiceCommands({ commands }: { commands: Command[] }) {
  const { isListening, transcript, start, stop } = useSpeechRecognition({
    continuous: true
  })

  useEffect(() => {
    if (!transcript) return

    const lowerTranscript = transcript.toLowerCase()

    for (const command of commands) {
      if (typeof command.phrase === 'string') {
        if (lowerTranscript.includes(command.phrase.toLowerCase())) {
          command.action()
        }
      } else {
        if (command.phrase.test(lowerTranscript)) {
          command.action()
        }
      }
    }
  }, [transcript, commands])

  return (
    <button onClick={isListening ? stop : start}>
      {isListening ? '🔴 Stop Voice Commands' : '🎤 Start Voice Commands'}
    </button>
  )
}

Usage:

export function App() {
  const commands = [
    {
      phrase: 'go home',
      action: () => router.push('/')
    },
    {
      phrase: 'open menu',
      action: () => setMenuOpen(true)
    },
    {
      phrase: 'search for',

    onResult: (transcript) => {
      setQuery(transcript)
    }
  })

  const handleSearch = () => {
    if (query) {
      // Perform search with query
      console.log('Searching for:', query)
    }
  }

  return (
    <div className="flex gap-2">
      <input
        type="text"
        value={query}
        onChange={(e) => setQuery(e.target.value)}
        placeholder="Search or speak..."
        className="flex-1 px-4 py-2 border rounded"
      />

      <button
        onClick={isListening ? stop : start}
        className={`px-4 py-2 rounded ${
          isListening ? 'bg-red-600 text-white' : 'bg-gray-200'
        }`}
      >
        {isListening ? '🔴' : '🎤'}
      </button>

      <button
        onClick={handleSearch}
        className="px-4 py-2 bg-blue-600 text-white rounded"
