Supported languages

Spiiksi understands 70+ spoken languages and interprets into dozens of languages, including Finnish, Swedish, English, Ukrainian, Arabic, Persian, Estonian and Russian. The full list is on the Languages page (/languages), with a page for each language.

One event can run many languages at once. Each costs per minute separately.

Default, Plus and Pro

Each listener language runs on a translation tier. Spiiksi picks it automatically; change it in Advanced settings under Translation quality.

Example data

Advanced settings → Translation quality.

  1. 1Spiiksi picks the tier; change it per language.
  2. 2Languages Default doesn't support use Plus automatically.
  • Default: recommended for the languages it supports. Fast, natural, best value. Supports English, Spanish, Portuguese, French, German, Italian, Japanese, Korean, Chinese, Russian, Hindi, Indonesian and Vietnamese.
  • Plus: covers every language and supports event-specific vocabulary and instructions. Languages Default doesn't support (for example Finnish, Swedish, Ukrainian, Arabic, Polish) use Plus automatically. Plus can also be chosen for a Default language; it is often more natural with tone and names and takes slightly longer.
  • Pro: highest quality for demanding events, with full interpreter guidance.

Plus and Pro are priced differently from Default. Current prices are on the pricing page; the pricing page also shows which languages are Plus.

Helping the interpreter

Interpreter instructions

Edit event → Interpreter instructions: free text sent to every Plus channel of the event. Put in names, terminology, the audience and the tone, e.g. "A Lutheran church service. The pastor is Anna Virtanen. Keep hymn numbers as numbers." Any language works. The interpreter never adds anything the speaker didn't say.

Example data

Tell the interpreter about your event before it starts.

  1. 1Interpreter instructions: names, terms, audience and tone.
  2. 2Names and terms: leave the translation empty to keep a name as is.

A single language can override it in its Settings → Interpreter context.

Names and terms

In a language's Settings → Delivery style → Names and terms, tell the interpreter how to translate particular names, abbreviations and terms:

  • "board" → "hallitus", "WHO" → "Maailman terveysjärjestö".
  • Leave the translation empty and the word is said as is. Useful for company and personal names.
  • Terms listed first are used first.

Delivery style

Settings → Delivery style changes how the interpretation sounds, not what it says: Mood, Energy, Formality, Drama, or name your own feeling (e.g. warm, solemn) and how strong it is. Reset style goes back to neutral.

Example data

Delivery style changes how it sounds, not what it says.

  1. 1Name your own feeling, and how strong it is.

Voice and behaviour

In a language's Settings:

  • AI voice: pick the voice. On Default the voice follows the speaker; choose Plus for a fixed voice.
  • Responsiveness: steadier vs. faster start.
  • Prefer safe output: when unsure, stay quiet rather than guess.
  • Keep segments brief: tighter chunks when the meaning stays intact.

Changes apply the next time that language channel starts.

Original audio and captions

Under Advanced settings → Audio to translate:

  • Also offer the original audio: listeners who understand the spoken language can listen without translation. Free.
  • Show captions: listeners can read what is said as it is spoken. Turning it on also offers the original audio. Captions cost per broadcast minute (price shown next to the switch).

Listeners can also read the interpretation of any language as text with Show text on the listener page.

Quality tips

  • A clean microphone signal matters more than anything else. See Audio setup and troubleshooting.
  • Set the correct spoken language.
  • Add names and terms before the event, and write interpreter instructions.
  • Test with Preview as a listener before the audience arrives.
  • If a language sounds off on Default, try Plus.
