Instructional designers
Scale narrated courses without scaling the budget
Professional voice actors charge per-word, which makes iteration expensive. FreeTextoSpeech lets instructional designers regenerate narration in seconds after each copy change, use the same voice consistently across a course, and ship multilingual versions without hiring a native speaker for each language.

The quick answer
Paste your script, pick a corporate voice (Jessica or Michael), generate, and import the WAV into Articulate Storyline, Rise, iSpring, or Captivate. Translate and regenerate per language to publish localized SCORM packages — all under one commercial license.
In four steps
Localization workflow
- 01
Translate your script
For multilingual courses, translate the English script into each target language up front.
- 02
Generate per language
Paste each translation, select the native voice (Dora for Spanish, Siwis for French, Alpha for Hindi), generate WAV.
- 03
Import into authoring tool
Articulate Storyline, Rise, iSpring, Adobe Captivate, Lectora — all accept WAV uploads natively.
- 04
Publish per locale
Duplicate the course, swap the audio track, publish each language as its own SCORM/xAPI package to your LMS.

Voice guide
Voice picks for corporate training
The wrong voice torches retention. Six picks calibrated to module type — corporate narrator, SME gravitas, compliance neutral, and onboarding warmth — so you can stay consistent within a course and still vary across a curriculum.
01 US
Adam
Corporate narrator
Best for
The default for most modules — onboarding, product enablement, manager training. Steady, professional, low theatrics. Pairs well with slide-driven content.
02 US
Sarah
Authoritative SME
Best for
Subject-matter-expert intros, leadership messages, and high-stakes compliance topics where you want gravitas without sounding cold.
03 UK
Daniel
British formal
Best for
Global rollouts where a UK voice signals corporate-headquarters provenance, financial services modules, and audit-track narration.
04 US
River
Smooth instructional
Best for
Long-form how-to modules where listener fatigue matters. Even tone keeps engagement steady across 10+ minute lessons.
05 US
Bella
Friendly onboarding
Best for
Day-one new-hire welcomes, culture modules, and any course where you want learners to feel greeted rather than instructed.
06 US
Liam
Neutral compliance
Best for
HR policy, security awareness, and annual recertification content — flat-affect delivery that does not editorialize on serious topics.

Best practices
Production tactics for instructional designers
Specifics on chunk size, animation sync, voice consistency across course updates, and the caption workflow that keeps you WCAG-compliant without manual timestamping.
- 01
Chunk lessons under 5,000 characters per slide module
The 5,000-character cap maps almost exactly to a well-paced two-minute audio block — about the natural attention span for a single learning objective. Treat one generation as one slide or one Rise block. If your script runs longer, the slide is doing too much work; split it.
- 02
Sync narration to slide animations in Storyline and Rise
In Storyline, drop the WAV on the timeline and use cue points to fire builds and bullet reveals. In Rise, attach audio to each block — block timing is automatic on play. Always edit the script to match animation pacing rather than forcing animations to match a finalized voice track.
- 03
Branded voice across modules, neutral voice for compliance
Pick one voice (Adam or Sarah is the safest pair) for any course in your branded curriculum and stick to it across modules and quarterly updates — voice consistency is part of brand consistency. Switch to a deliberately neutral voice (Liam) for compliance and legal content where personality could read as bias.
- 04
Pair audio with transcripts for WCAG 2.1 AA
Audio alone is not accessible. Generate the audio from your written script, then keep that exact script as a downloadable transcript and feed it into your authoring tool as closed captions. WCAG 2.1 AA Success Criterion 1.2.2 requires synchronized captions for prerecorded media — the script you already wrote covers it.
- 05
Caption sync without manual timestamping
Most authoring tools auto-generate captions when you import a WAV with a matching script. In Storyline use the Captions panel and import the script as SRT or VTT; Rise uses block-level closed captions. Voice consistency across regenerations means caption timing rarely drifts when you update a single line.
- 06
Future-proof voice selection for course updates
Record the exact voice name and any speed adjustments in your course documentation. When a regulation changes 18 months later and you need to regenerate three slides, picking the same voice keeps the update invisible to learners. Mismatched voices mid-course flag the patch instantly.
Honest comparison
Vs Articulate and Vyond built-in TTS
Authoring tools bundle their own TTS. It works, but you trade portability and cost predictability — the audio lives inside that vendor's package and pricing scales with seats and learner volume.

FAQ
Frequently Asked Questions
01 Does AI narration meet accessibility requirements like WCAG and Section 508?
Yes. Natural AI voices paired with synchronized captions satisfy WCAG 2.1 AA and US Section 508 guidelines for multimedia. Always provide captions or a text transcript alongside audio.
02 Can I import WAV into Articulate Storyline, Rise, or iSpring?
Yes. All major authoring tools accept WAV uploads for slide narration. Import the WAV, assign it to a slide or block, and publish as SCORM or xAPI.
03 Is it suitable for corporate compliance and onboarding courses?
Yes. Commercial use is allowed, including internal training, LMS-hosted modules, and paid courses. Multiple languages let you ship localized versions without re-recording.
04 Does it work with Moodle, Canvas, or Blackboard?
Yes. Any LMS that supports audio file uploads accepts WAV. Alternatively, embed the audio in a SCORM package built in your authoring tool and upload the package to your LMS.
05 How do I localize a course into 9 languages?
Translate the script, paste each translation into FreeTextoSpeech, select a native voice (Dora for Spanish, Siwis for French, Alpha for Hindi, etc.), generate and download. Replace audio tracks in your authoring tool.
06 Is the audio SCORM 1.2 / 2004 / xAPI compatible?
The audio files themselves are plain WAV — format-agnostic. SCORM and xAPI compatibility comes from your authoring tool (Storyline, Rise, Captivate, iSpring), not the audio. Import the WAV into a slide or block and publish the package as SCORM 1.2, SCORM 2004, or xAPI from the authoring tool. Your LMS sees a standard package with an embedded WAV.
07 Can I reuse the same audio across multiple courses without re-licensing?
Yes. Generated audio is licensed for commercial use with no per-project, per-seat, or per-learner fee. Drop the same WAV into onboarding, then into a refresher course six months later, then into a partner-facing version — no re-licensing, no renewal, no learner-count cap.
08 How do I handle technical jargon and acronyms in compliance training?
Spell tricky acronyms phonetically in the script (write "H I P A A" or "H-I-P-A-A" instead of HIPAA so the voice reads each letter). For brand or product names that get mispronounced, write the phonetic spelling, generate, listen, and adjust. For Latin medical or legal terms, break syllables with hyphens. The 5,000-character limit per generation is generous enough to iterate quickly.
