iSpeech is a tool that provides text-to-speech and speech-to-text services for developers and organisations so they can add voice-output, voice-input and accessibility features to apps, websites and learning content.

Alternative To

iSpeech is a cloud-based voice platform that offers two main capabilities: (1) converting text into spoken audio (TTS — text-to-speech), and (2) converting spoken audio into text transcripts (ASR — automatic speech recognition). It provides APIs and SDKs for integration into web apps, mobile apps, and server-side environments.

If you’re building an app, website or course content and you want to add voice (either output or input) — for accessibility, learning, voice assistants, audio-articles, IVR/phone systems — iSpeech allows you to implement that without hiring voice actors or building your own speech tech stack. For example, their site says publishers previously would pay thousands of dollars for voice talent; iSpeech claims major cost savings. Also important for accessibility and learners: converting text to spoken audio helps auditory learners and users with vision or reading difficulties.

You sign up for service, get an API key, choose a voice (gender, language, speed, tone) and send text via API or use their web/mobile tools; the service returns an audio file (TTS) or text transcript (ASR). They support multiple platforms (mobile, web, server) via SDKs. On pricing, they offer free personal-use options and paid tiers for commercial/API use. Early caution: check the usage caps, rights/licensing for commercial use, and ensure the voice style and languages fit your target audience. Also ensure latency, format output (MP3, WAV etc) and regional language support meet your needs. For example they note a personal account cap of 100,000 words per conversion for certain plans.

FAQ

Can I use the audio generated by iSpeech commercially (e.g., for a podcast or ad)? ▼

Yes — but you must check the plan you’re on. The personal free/basic plans are for non-commercial/personal use only; commercial/distribution use typically requires a paid/commercial license. Their policies note “If you want to use iSpeech for anything other than Personal Use, you must contact us.

What are the usage limits or quotas? ▼

For personal use they list caps: for example the “Plus” plan is up to ~4,167 words (≈30 minutes) and the “Premium” up to ~100,000 words (≈12 hours). (ispeech.org) For API/integration use there are credit-based pricing (e.g., 2,000 credits = US$50) with per-word/transaction pricing.

Can I integrate iSpeech into a mobile app or server-side backend? ▼

Yes — iSpeech offers SDKs and APIs for web, mobile (iOS, Android, BlackBerry) and server/desktop environments. You’ll get an API key and can use mobile development vs production servers.

What languages and audio formats are supported? ▼

They support multiple languages (e.g., the web page mentions 28 languages for the free TTS version) for text-to-speech. (ispeech.org) Audio output formats include WAV, VOX, MP3, OGG, AIFF, AU, FLAC etc.

Does iSpeech use my text/audio to train its models? ▼

Not clearly detailed publicly. There is no obvious statement about whether user input is used for training. If you have strict data-governance or privacy requirements you may need to ask the vendor directly.

What happens if I need very large scale or custom voices? ▼

For very large scale (high volume) or custom voice/branding, you should contact their sales team—they list “Creative Pricing / One-time fees / Custom Voices / Custom Language models” under their developer pricing page.
