Speechgen - 2026 Pricing, Features, Reviews & Alternatives

Speechgen is a cloud-based AI text-to-speech platform that converts text, documents (PDF, DOCX), and subtitle files (SRT, VTT, SUB) into audio, handling up to 2 million characters per generation. The platform provides access to 5,000+ neural voices across Standard, Pro, and HD quality tiers in 150+ languages and regional accents, with output formats including MP3, WAV, FLAC, OGG, and OPUS at bitrates from 8 kHz to 320 kbps. All features run entirely in a web browser with no software installation required, and a REST API supports integration into external workflows via tools such as n8n, Make, and Zapier.

Core capabilities include multi-voice dialog mode for assigning distinct voices to different text sections and merging them into a single audio file, audio segmentation via cut tags for exporting separate files from one script, and subtitle-to-audio conversion that parses SRT, SUB, and VTT files and auto-syncs speech speed to each timestamp. AI voice cloning builds a personal voice model from a 10-60 second audio sample in under one minute, usable across 15 languages. An intonation graph editor provides sentence-level pitch control, while adjustable speed, pitch, and pause settings, SSML tag support, and a built-in library of 1,000+ royalty-free AI-generated background music tracks across 133 categories round out the audio production toolkit. Audio-to-text and video-to-text transcription with speaker labels and timestamps are supported across 140 languages.

Speechgen serves a broad range of industries including e-learning, media and entertainment, marketing, healthcare, tourism, software development, and broadcasting. Target users span individual content creators, instructional designers, marketers, small businesses, localization teams, game studios, and developers. Pricing operates on a pay-as-you-go credit model with no subscription required; credits are shared across all features and voice tiers, and a smart sentence-level caching system reuses previously synthesized audio for 7 days to reduce costs on iterative projects. A commercial license is included on all plans, and a free tier provides 1,000 characters without sign-up or watermark.
