[Open the source ](https://respeecher.com/) ## Two ways to produce a voice Respeecher works with recorded speech and text. With recorded speech, the original performance helps retain delivery while changing the voice. Text synthesis creates speech from written words. These are different tasks: successfully converting an actor’s recording does not prove that text synthesis will reproduce its rhythm or emotional details. Current documentation separates the Space API and Marketplace API. Space primarily covers streaming speech synthesis and voice applications. Marketplace covers speech conversion, projects and batch operations. Their addresses, keys and result retrieval differ. Check before transferring an authentication example from one interface to the other. ## An example using an authorized voice For a practice project, record a short character line yourself or use a recording with the performer’s permission. Select an available voice and compare the processed version with the source at equal volume. Listen separately to quiet words, sustained vowels and transitions from calm to more expressive speech. Use the same line for text synthesis, but assess it as a new performance. Check names, meaningful pauses and missing words. If the timbre fits but the intonation changes the meaning, the result is not ready for the scene. Keep the approved source and the selected mode’s settings. ## What to clarify before integration Rights to the voice and source recording remain essential. Respeecher’s public studio portfolio shows how the technology is used; it does not authorize users to reproduce voices from those projects. Prepare your advertising or artistic material from authorized sources within the selected access terms. Check trial access, production volumes and contractual terms for the specific product. API use requires a key and cost tracking. For interactive applications, also assess failures and latency; for studio work, allow manual replacement of an unsuccessful excerpt. One audio demo is not enough to make these decisions. ## Suitable tasks - Convert an authorized vocal performance - Create synthetic character narration - Integrate streaming TTS through the Space API Features ## Strengths - Separate studio and streaming workflows - Professional portfolio and documentation for two APIs Things to consider ## Limitations - Space and Marketplace have different keys and conditions - A similar voice does not grant rights to use it ## Selection and conditions Free access Not confirmed Trial period Not confirmed No sign-up required Not confirmed Russian interface Not confirmed Local installation Not confirmed API Yes “Not confirmed” means there is not enough information. The feature may still be available; check the developer’s terms. Input formats Text, Audio Result Audio ### Terms Space and Marketplace use separate workflows and API keys. Check trial and production costs for the chosen product, and obtain rights to the voice you use. From task to first result ## Practical example Task Convert an authorized vocal performance What to prepare Your own short instruction script and a voice you have permission to use for the intended purpose. ### Task brief or prompt Hello. We’ll now check the notification settings. First, open your profile. Then go to settings and find notifications. After changing the settings, save your changes. ### Expected result A draft narration to listen to; pace, voice and pauses are controlled by the settings available in the service. ### How to check the result - Listen to names and abbreviations separately. - Check the pauses, volume and voice rights. An editorial teaching example of a task brief, not the result of hands-on testing of the service. Check that the required mode is available, that you have rights to the source material and that the intended use of the result is permitted.
