There's now a command line for Speechify.
Read storyBuild a Slack bot that reads channel messages aloud with the Speechify API. Wire events, synthesize audio, and post the clip back to the channel.
Give the Speechify text-to-speech API a URL and the page comes back as narrated audio. Fetch, extract the article text, chunk on sentence boundaries, synthesize each chunk with POST /v1/audio/speech.
The safeguards SpeechifyAI operates to prevent synthetic voices being used for election misinformation, and the commitments behind them.
A voice agent's tool call happens inside a turn the caller is waiting through, which makes it a latency decision before it is an architecture one. The rule: reads that return fast run inline, writes and slow lookups get a receipt and finish asynchronously.
The three ways an ecommerce brand answers the phone, normalized to cost per talk minute so they are comparable. Outsourced call centers run $0.35 to $1.35 a minute and voice agents run under $0.08 all-in, but containment rate decides more than either number.
What engineers actually use to add voice to web and mobile apps, and the four decisions that matter: the browser's built-in API versus a cloud one, streaming versus batch, where the key lives, and how to keep audio playing on iOS.
Nine voice agent platforms priced on what a minute actually costs once LLM, speech and telephony are added. Most headline rates are platform fees.
The tools for producing narration without hiring voice actors, compared on cost per finished hour rather than per seat. Studio subscriptions cap downloaded minutes; per-character APIs do not. One hour of audio runs from $0.31 to $40 depending on which you pick.
Which speech platform to pick when your chatbot has to talk. The decision is not voice quality, it is whether you need a TTS API or a full voice agent, plus how the model reads account numbers and order IDs back to a caller.
Generate the same script in English, German, Spanish, French, Italian, and Portuguese with the Speechify TTS API. Pick a simba-3.0 voice for each locale, call POST /v1/audio/speech per language, keep the key server-side.
The AI SDK ships generateSpeech() but no Speechify provider. So we wrote one: a dependency-free custom speech model that maps POST /v1/audio/speech onto the SDK's SpeechModelV4 interface, key held server-side in a Next.js route.
simba-3.2 is now the recommended Speechify TTS model, and GET /v1/audio/models lets you discover it at runtime instead of hardcoding a model list. What shipped, which voices it serves, and how to move off simba-3.0.
The 10 text to speech APIs worth evaluating in 2026, ranked on blind-listener scores from Artificial Analysis and priced per million characters.
Clone a voice from a browser upload, synthesize speech with it, and keep your API key server-side. A working Next.js voice cloning app built on the Speechify API, no GPU required.
Stream Speechify TTS as raw PCM, keep the API key server-side, and schedule each chunk into the browser's Web Audio API for low-latency playback.
Point Deepgram Voice Agent at the open-source tts-shims OpenAI-compatible proxy to speak with a Speechify voice. The shim answers Deepgram's open_ai TTS request and keeps your Speechify key server-side.
Use SSML emotion tags, pauses, prosody, emphasis, and pronunciation aliases to shape Speechify TTS output from one API request.
Simba 3.2 is evaluated on Artificial Analysis' independent TTS benchmark and on Voice Arena's blind, listener-voted board. Streaming ~430ms to first byte, from $6 per 1M characters, with production-grade quality.
Turn long-form ePub or Markdown into a single narrated chapter MP3 with a runnable Python demo: chunk on sentence boundaries, synthesize each chunk, stitch with ffmpeg.
Speechify is now a direct provider in speech-sdk. Switch existing calls over with a factory function and an API key, no new client required.
Clone a voice from a short sample and use it to narrate dynamic video content programmatically via the REST API.
Baseten published a case study on the SpeechifyAI voice agent stack. This is our view on why model co-location matters for live calls.
