Our verdict on iSpeech

iSpeech provides text-to-speech and automated speech-recognition services through web interfaces, APIs, and SDKs. It is aimed at developers building web, iOS, Android, mobile, desktop, or server applications that need synthesized speech, downloadable audio, or programmatic controls. The service supports multiple voices and locales, along with SSML, MathML, word position markers, and viseme data.

The pricing structure covers personal use, recording limits, API usage, and mobile distribution. The Basic plan is free for personal use. Plus costs $2.95 per month or $19.95 per year and supports recordings up to 30 minutes, approximately 4,167 words. Premium costs $3.95 per month or $29.95 per year and supports recordings up to 12 hours, approximately 100,000 words. Pay Per Use costs $50 per 2,000 credits, with one credit equal to one TTS word, while Pay Per Install costs $0.25 per install for mobile usage and unlimited dynamic TTS. Commercial use and API access follow separate pricing or terms.

For technical teams, iSpeech’s strongest fit is its range of integration paths and output controls. REST, JSON, and XML interfaces work alongside SDK support for mobile, Java, .NET, JavaScript, and other applications. Developers can adjust speed, pitch, bitrate, frequency, and bit depth, then export to formats including AIFF, MP3, OGG, WMA, FLAC, WAV, A-law, µ-law, VOX, and MP4. Choose iSpeech when format coverage, API access, and low entry pricing matter. Consider another service if you need a simpler pricing structure or a plan designed around commercial and API access without separate terms.
